It’s becoming a more common expectation — and even a mandate on some job sites — for contractors to convert from traditional shielded metal arc welding (SMAW) to wire welding processes for pipeline construction and repair. Make sure your team is prepared.

Welding cart: Wire-feed welders can weigh up to 75 pounds, so build or invest in a welding cart to increase portability. Awl or carbide scribe : to mark cut lines.
welding, the wire is classified using 100% CO 2; however, argon-oxygen-carbon dioxide coinations may be used based on the oxygen equivalent. For full details of gas coinations refer to CSA Standard W48. Some common mistakes with Block 2:
FCAW (Flux Cored Arc Welding): The FCAW process is very similar to Mig welding, although it does not always use a shielding gas. Also, instead of a bare wire, a tubular wire containing granular flux is used. When a self-shielding flux is used, no gas shielding

Joining Similar Materials The table gives typical selections of welding consumables and basic designations for wire electrodes and filler wire/rods. It does not indie the silicon-alloyed variants used for MIG welding or the variants of covered electrodes or wire-flux coinations for submerged arc welding.
Best Practices for Success in Self-Shielded Flux-Cored Welding Self-shielded flux-cored arc welding (FCAW-S) offers numerous benefits, including good weldability, high deposition rates, and excellent chemical and mechanical properties. These make the process a
The best gas for MIG welding and the types of welding gases used are namely: Welding Gas for Carbon Steel When it comes to the gases used in normal welding for Carbon steel , many welders used the C25 mixture that consists of CO2-25% and Argon gas – 75%, because CO2 cannot be used separately in some cases as it creates a deeper penetration along with lots of smoke and even may …

FCAW is similar to MIG, but instead of a wire and shield gas, it makes use of a hollow wire that is filled with flux. Flux-cored arc welding is an easy process to learn and is, therefore, the best …
6/8/2020· According to OSHA’s Fact Sheet, MIG welding (GMAW) or flux-cored welding (FCAW) using currents of 60 to 500 amps requires a minimum lens shade level of a DIN nuer 10.Both ANSI and AWS are more cautious, recommending a shade nuer 11 for welding at 60-160 amps, a nuer 12 for 160-250 amps, and a nuer 14 for 250-500 amps.
