Re: [PSUBS-MAILIST] a-455 steel



Hi again Randy,
 
Personally I think that this dual shield method is ideal be cause you get most of the speed of the mig and most of the benefits of stick. It is the method that I am using. Because wire is much less dense than a stick it is very important to weld steel preheated to about 200 degrees for best results, especially in heavier sections to assure good penetration. I got the 200 deghree figure from Dan Lance who really is our welding guru and the expert in this area. 
 
I do know that Dan prefers stick welding from conversations with him.
 
Best Regards,
 
Jim K

HI Jim
 
My plans are to use the dual shield method whenever i use mig on pressure related areas. That is I will use gas in conjuction with the shielded wire. Do you know of a problem with this method for our application?
thanks
Randy
