Filler Metal Options to Improve Productivity and Quality in Process Pipe Welding
To gain a competitive advantage in process piping applications, some contractors have chosen to convert from Stick or TIG welding to wire processes. These wire processes can speed production, ease training and produce high quality in process pipe applications. With this conversion, however, comes the question of filler metal selection. It is critical for contractors to select high quality filler metals for every weld pass in order to prevent potential defects and to ensure the weld quality and productivity needed to gain a competitive advantage from a wire process.

Avoid These 13 Common Pitfalls in Process Pipe Welding
There are a number of common elements in pipe welding and fabrication that can lead to problems. These include everything from improper shielding gas and drive rolls to choosing a MIG gun with too low of an amperage rating. As companies push to train new welders, work with new materials, increase quality and productivity, and improve safety, it is important to focus on some of the basic variables in the pipe welding process that can affect these efforts.

Compared to similarly sized machines, the DC TIG/Stick-capable Maxstar 280 TIG welder delivers up to 280 amps of output power and provides the ability to weld metal up to 3/8-inch thick — yet is significantly lighter (only 47 lbs), more portable and uses less energy than machines of similar output capabilities. Intended for industrial applications, construction and heavy fabrication, the Maxstar 280 incorporates advanced technologies to improve weld results and a smooth, stable arc to handle any size job. The base model provides an operator-friendly interface for intuitive operation, while the DX model addresses demands for precision fabrication, adding extended ranges for maximum DC capability.

Simplified and optimized specifically for pipe welding in the refinery, petrochemical, power generation and HVAC industries, the new PipeWorx 350 FieldPro System delivers simplified cable management, complete control at the weld joint, arc performance optimized for critical pipe welding and is designed and built to withstand harshest field environments. The multiprocess system provides conventional Stick, TIG, MIG and Flux-Cored processes. The system can also run the advanced Regulated Metal Deposition (RMD®) and Pulsed MIG processes, which can help reduce weld failures and eliminate backing gas on some stainless and chromoly applications.

The Trailblazer 325 Diesel welder/generator delivers multiprocess welding capabilities and smooth generator power, with innovative technologies designed for the professional welder. The welder/generator is designed to extend runtimes by 55 percent, reduce fuel use by as much as 25 percent and reduce noise by 40 percent for a safer, more productive jobsite. A redesigned case — now 7 in. shorter and up to 80 lbs lighter — provides a smaller footprint, allowing a work truck to carry more equipment and heavier payloads. Two industry-exclusive technologies — both standard features — anchor the new Trailblazer 325 Diesel welder/generators: Smart-Cor™ technology and Auto-Speed™ technology.
