For applications > 4 mm. In contrast to spray the pulsed process with an 0.045 wire can provide lower weld heat input for heat sensitive applications. For greater weld fusion or improved arc consistency with automated welds, consider spray.
 

If the steel parts have mill scale or surface contaminates that effect the MIG weld transfer, weld quality or the arc stability, it's time to consider gas shielded flux cored. Do not use the all position flux cored wires if most of the flux cored welds are made in the flat position. Use the E70T-1 wires.
 

Forget pulsed MIG when consistent quality, vertical up welds are required for steel or stainless >3/16, >4.8 mm, consider instead all position, E71T-1 gas shielded flux cored wires with argon 15 to 25% CO2. FCAW electrode diameters 0.035 to 0.052 (1 to 1.4 mm) are recommended. From a weldability perspective, and its weld current range and deposition potential, my first choice has always been the 0.045 (1.2 mm) E71T-1 wires.

NOTE WHEN MANUAL CODE WELDS AND ALLOY WELDS ARE REQUIRED TIP TIG SHOULD BE THE FIRST WELD PROCESS OF CHOICE. www.tiptigusa.com


To optimize all your MIG and flux cored welds you may want to consider my book "Gas Metal Arc and Flux Cored Weld. For the book and the the most effective, CD, power point, FCAW process control training program ever developed, click.
