9 WELDING

9.1 GENERAL Approved welding procedure specifications and procedure qualification records

(WPS & PQR) will be used. Ref. T-4.250.938. Qualified welders are used for the welding activities at TSF area. Welding shall not be done when the ambient temperature and weather conditions

is below specified temperature without preheating; when surfaces to be welded are wet or exposed to rain, or high winds; nor when the welders are exposed to inclement conditions.

Random visual inspection of all welds shall be performed during execution of works.

The welding process shall be SMAW and /or GMAW, and/or OAW, and /or FCAW and/or GTAW.

9.2 PREPARATION OF BASE METAL Surfaces and edges to be welded shall be free from loose scale, slag, rust, grease, paint, and any other foreign matter and mill scale.

9.3 ASSSEMBLY Those parts to be joined by fillet welds, and separations between laying surfaces

to lap joint and of butt welds landing on a backing shall be brought into as close contact as practicable.

Those parts to be joined by groove welds shall be brought into correct alignment. Those members to be welded shall be held in the correct position by bolts,

clamps, wedges, guy lines, struts, or other suitable devices, or by tack welds, until welding has been completed. The use of jigs and fixtures is recommended where practical.

Tack welds shall be subject to the same quality requirements as final welds. Temporary welds made for erection purpose shall be sufficiently strong to

withstand all anticipated erection loads. All structural steelwork shall remain accurately aligned during bolting and welding

work, Ladders, lugs and hooks welded to structures for the purpose of erection and

safety in accordance with the construction drawings shall not be removed, unless otherwise specified or requested.

9.4 FILLER METAL All filler metals that have been removed from its original packaging shall be handled so that they do not absorb moisture. Wet electrodes shall not be used. Low-Hydrogen electrodes shall be dried in accordance with the manufacturer's instructions before use. Electrodes shall be kept in a quiver, which prevent them from atmospheric moisture. Ref.: T.4.250.931.

9.5 PREHEAT AND INTER-PASS TEMPERATURE Prior to welding, the base metal shall be preheated as required to the applicable WPS & project specification. Where the base metal temperature is below 5C, the base metal shall be preheated to at least 50C and that temperature shall be approximately maintained during welding. Temperature control can be carried out by Tempile stick, (or) digital pyrometers, calibrated according to calibration procedure T-4.250.915.

9.6 WELDING PROCEDURE

9.6.1 GENERAL Arc strikes outside the area of permanent welds not permitted on any base

metal. Before making the subsequent welding pass, all slag shall be removed and

adjacent base metal shall be brushed clean. Groove welds shall be terminated at the ends of a joint in a manner that will

ensure sound welds. Where possible, this shall be done by using extension bars or run-off plates.

Steel backing, if used, shall be made continuous for the full length of the weld. 9.6.2 WELDING CONTROL

The classification and size of electrodes, electrode-arc length, voltage, and amperage shall be specially selected to suit the thickness of the materials being welded, type of groove, welding position, and other circumstances relevant to the work. Welding electrodes, which are suitable for each steel grades, shall be selected by manufacturer's recommendation.

When welding in the vertical position, the progression of all passes shall be upwards.

The root of groove welds with no backing plate shall be gouged back and re-welded to produce sound metal fusion throughout the entire cross section.

9.7 INSPECTION TOLERANCES AND CORRECTIONS FOR WELDING Assembly and weld tolerances shall be based on the supplier drawings and AWS D.1.1 the alignment, groove angle, root opening, and cleanliness of the surfaces to be welded shall be inspected prior to welding for compliance with the tolerances. Members distorted by welding shall be straightened by mechanical means or by carefully supervised application of a limited amount of local heating.

10 NON-DESTRUCTIVE EXAMINATIONS Dye Penetrant Testing or Magnetic Particle Test shall be done on 10% of all butt-welding. The procedure shall be according to section 6.14 of AWS D.1.1, unless otherwise specified.

11 INSTRUCTIONS Welding and cutting normally produce fumes, gases & heat and may result in ultra-violet radiation. The main sources of hazard likely to be encountered are: High temperature causing burns and fires Electric shock, which could be fatal Fumes and gases, liable to cause injury to health Airborne of metal slugs from cutting / grinding Eye injuries. Thermal radiation causing burns and arc eye. Gas leaks from Oxy/Acetylene bottle/Fire/Explosion.

11.1 CUTTING AND BURNING Follow safety precautions listed below: All employees engaged in oxygen / Acetylene welding, or torch cutting must wear

appropriate protective coverall clothing, long leather gloves, safety steel toe shoes, etc. The assistant must wear a minimum of goggles for eye protection, and gloves.

Oxygen and acetylene cylinders in use must be secured to a welding cart, or other suitable structure.

All oxy/acetylene equipment must be inspected prior to use including regulators, hoses, flash back arrestors, torches, etc.

Hot work permits must be obtained prior to welding and / or torch cutting where any flammable liquid and/or gas exist. Sometimes gas test must be carried out prior to welding and the area must be clear of flammable gas/liquid. Especially it's mandatory when working on pipelines for repairing jobs.

Other combustible materials such as paper, plastic trash, etc must be moved out of the area before welding or cutting.

Cylinder caps must be replaced on oxygen and acetylene cylinders prior to moving to a new location.

Flash back arrestors must be on all gauges (sometime fitted on the cutting outfit if hose is too long).

Take precautions to prevent oil and grease from getting inside oxygen regulators or on oxygen valve threads.

Use forced air ventilation when welding or cutting is done in any confined space. Use isolation booth to prevent sparks from flying.

11.2 ARC WELDING Follow safety precautions listed below: Proper coverall, steel tip shoes, long leather gloves, face mask must be used during all

welding works. Other protection, such as a welder's jacket may be necessary. The welder's assistant will have to wear goggles for eye protection and the remaining PPE stands same as the welders.

Ensure that appropriate hot work permits have been issued and a copy has been issued to the supervisor in charge.

Some times gas test must be carried out prior to welding and the area must be clear of flammable gas/liquid. Especially it's mandatory when working on pipeline for repairing

jobs. Other combustible material such as paper, plastic trash, etc, must be moved out of the area before welding or cutting.

Install welding screens to prevent other persons getting flash when possible. If welding above ground level, contain hot slag with suitable sheeting and Fire

extinguishers are within the work area. Ensure ground return clamps are in good conditions and located as close as possible to

the work position. Ensure that all drains within 20 meters are covered. In confined spaces ensure there is adequate ventilation, and use respiratory protection

whenever necessary & the appropriate permits are in place. Ensure the welding generators are grounded properly when in use. Use forced air ventilation when welding or cutting is done in any confined space.

11.3 COMPRESSED GAS CYLINDERS Compressed gas cylinders must be handled with care and stored in a secure upright

position. Cylinders caps must be in place when cylinders are not in use, especially when cylinders

are being transported. Cylinders should be stored securely to prevent cylinders from falling over. Regulators should be inspected daily. Inspection should cover whether the gauges are

accurate, dents or cracks in the gauge covers, hose connections, flash back arrestors to be fitted to all gauges, etc.

Cylinders should never be used while lying on their side. Cylinders in use should be secured in an upright position.

Never oil or grease cylinder valves and/or regulators. 11.4 TRAINING (GRINDING WORKS)

Only competent persons are permitted to operate tools utilising abrasive wheels, cutting discs abrasive tips and flappers. Training and instruction must be provided before any person can be authorised to mount wheels on pedestal grinders or change abrasive wheels, cutting discs tips or flappers. Supervisor to ensure right disk for the job is used. i.e. cutting disc, grinding disc. The correct personal protective equipment must be used at all times when using any grinding or abrasive tools. This consists of proper gloves, goggles, steel tip toes shoe, etc. Double eye protection to be worn when cutting or grinding (Safety glass & Face shield). Ear plugs to be worn for ear protection. Care must be taken to minimise the risk of fire by removing all potential flammable materials from the immediate work area. Precautions must also be taken to control or contain sparks and suitable fire fighting equipment must be readily available at site or working area.

11.5 LIFTING SLINGS There are two types of lifting slings used on this job, wire slings and webbing slings. It is very important that they are used and stored correctly.

Always use the right slings for the job, each sling has its safe working load (SWL) printed

or attached to the sling. Never try to make up, prefabricate lifting equipment. Do not use a sling if there is no SWL written or attached, remove the sling and give it to

your supervisor. Never tie knots in webbing or wire slings. This will damage the sling and it will need to be

discarded. Always check a sling before use, look for tears, cuts and broken wires and if you have

any doubts about the sling show it to your supervisor. Wire slings must not have more than five broken wires in one lay and must not be crushed or kinked. Nylon slings must not be knotted or torn in the centre of the sling.

Never drag a sling from under a load if it is not free. Webbing slings should not be dragged through oil or along the ground. Store the sling in

a rolled position making sure the sling is dry and stored in a dry place. Be careful not to wrap the edges of the sling on sharp corners. Use packing materials

rubber, wood, cloth anything that will keep the slings surfaces away from sharp edge. Always attach the sling properly to the load. Do not use a combination of wire and

webbing slings together, webbing will be cut by the wire sling. All lifting equipment must be inspected, documented and colour coded.

12 QUALITY ASSURANCE A Quality Assurance System shall be operated conforming to related standards.
