P-625 Computerized Welding Machine

CRC-Evans Automatic Welding

High production welding on all diameters ofonshore and offshore pipelines has just gottenmore efficient with the P-625 compact weldingsystem. The reduced size and weight of the weldingbug improves the overall welding cycle time andallows more efficient use of two machines on smallerdiameter pipe. The P-625, while compact, is robust.The system is designed for ease of maintenance and portability. The P-625 features reduced cablingto make initial set-up fast and efficient, a greatadvantage should field conditions require a breakdown of the welding station for moving. In addition,fewer cables means better reliability. The system is

operator-friendly and self-diagnostic should anyproblems occur, making trouble shooting a breeze.The P-625 is the next generation of high-techautomated pipeline welding.

The P-625 is the culmination of a meticulous designprocess that couples our extensive expertise inautomatic welding with detailed customer feedback.We asked industry insiders what features wouldmake up the ideal small-diameter machine and whatadvancements were desired – and we delivered on allcounts with the most leading-edge technologyavailable.

Repeatable Perfection

It’s not enough to produce a high-quality weld. Youneed to be able to do it consistently, time after timeafter time. It takes a collection of integrated high-tech features to deliver this kind of repetition – all ofwhich are aboard the P-625.

For starters, the unit uses pulse MIG weldingtechnology. It also employs full through-the-arctracking, which keeps the torch and bead in perfectposition through computerized monitoring andcontrol, thus maximizing weld speed and quality inboth vertical and horizontal applications. The term‘computerized’ is in fact the most accurate way todescribe all P-625 features.

Every aspect of the machine is fully digital, frompre-weld programming to real-time operation topost-project assessment. These are not individualdigital features, but rather a completely integratedsystem. A PDA interface allows you to programweld parameters in the office and then wirelesslydownload them directly to the P-625 in the field. Inturn, you can upload real performance data onevery weld and carry it back to the office for qualitycontrol analysis and reporting. In the end you knowthat every weld is on spec, and you have the proof.

Smart Machine, Smart Investment

Full digital-to-digital operation means human erroris taken out of the productivity equation. The P-625simply follows encoded weld parameters, givingyou complete control over the welding process andcomplete assurance of job quality. When you’reready to change weld parameters, the P-625 isready, too. You can make changes to the controlsoftware in the field, on the fly – and quickly put themachine back to work.

The P- 625 is certainly a technological wonder rightnow. But it is also designed to stay that way intothe future. It is built on scalable architecture,meaning that as we develop new advancementsthe machine will be able to accommodate them.Your smart investment today will seem evensmarter tomorrow.

Total Project Support

The P-625 delivers outstanding performance on itsown. But it’s the people, expertise and worldwideresources we put behind the machine that takeyour results to the next level We call this TotalProject Support™ – TPS™.
