![]() ![]() When a weld shop uses Pulsed MIG or Spray Transfer on steels and alloys > 1/4, (> 6 mm), they typically should see superior fillet or groove weld fusion from the MIG spray mode and that applies to all metals. MIG WELD DEFECTS THAT CAN BE GENERATED BY THE WELD PROCESS RATHER THAN BY THE WELDER. Most weld personnel are not aware that both GMAW (MIG), and also the Rutile EXOT-1, Gas Shielded Flux Cored weld processes have weld metal transfer and arc energy / plasma characteristics in which since the inception of these weld processes, have produced a poor relationship between the weld mass delivered, the weld speeds that result and the amount of weld / part energy generated. T HE RELATIONSHIP BETWEEN MIG WELD MASS & WELD ENERGY. Then one could ask why there is the forty plus MIG gas mixes available to an industry that only needs four MIG mixes. And lets not forget the common global lack of front office ability for weld process ownership and their general lack of awareness of weld process controls, best weld practices and weld costs. most of whom have never worked in or ran a weld shop. In an industry in which weld personnel playing around with MIG and flux cored weld equipment controls has been the norm for seven decades, it’s hard for some to see the weld reality of the arc weld processes they daily use.ĭuring the last five decades, in my role as Weld Equipment or Weld Training Manager with Airgas, Praxair, AGA, Liquid Carbonic, and also as the North American ABB Robot Weld Manager, I am well aware of the decades of sales induced, exaggerated Pulsed MIG steel and alloy steels weld claims with MIG equipment that in many instances was often loaded with useless electronic bells and whistles.Īdd to this, the decades of dependence of the majority of weld shops for weld advice from weld sales-reps. ![]()
