Guide to TIG Welding Basics - MillerWelds
2022年10月11日 · For steel and steel alloy welding, switch your amperage setting to DC TIG or DCEN. (For stick welding, switch your amperage setting to DC Stick or DCEP.) Prepare tungsten: Grind your tungsten to a point. When welding on aluminum, the tungsten will begin to form a ball. If the ball grows to the same diameter as your tungsten, repoint the tungsten.
Guide to Pulsed MIG Welding in Manufacturing | MillerWelds
2017年2月2日 · • Stainless steel — Pulsed MIG typically uses a 98% argon and 2% CO2. Gas blends should limit CO2 content to no more than 5% to prevent sensitization. Watch stickout and technique: The recommended welding techniques for pulsed MIG are similar to the techniques used for spray transfer. Maintain a stickout of 5/8 to 3/4 inch, with ...
Want To Improve Results When MIG Welding Stainless Steel?
2021年9月13日 · MIG welding stainless steel. Stainless steel is ideal for welding applications that require long life and corrosion resistance — from fabricating fire pits and smokers to repairing damaged household items. MIG welding stainless steel can provide benefits for efficiency while still producing high-quality welds, but it’s important to keep in ...
Welding Stainless Steel Tube and Pipe: Maintaining Corrosion
2013年1月22日 · Operations typically use TIG welding for welding stainless steel tube and pipe, and it remains the optimal solution for extremely high purity applications on tube or pipe at or below 6-inch diameter and schedule 10 wall thickness. The preferred method for high purity food-grade stainless steel is an autogenous TIG square butt weld.
Mig welding stainless steel. - Miller Welding Discussion Forums
Today I tried my first ever stainless steel welds with the Millermatic Passport. Wire used was 0,030" 308 LSI and shielding gas was 98% Argon/ 2% CO2. Layed a few beads on some scrap 304 tubing, 0,10" thick I have. I followed the chart settings for tri-mix and set the machine in stainless mode DCEP. To my surprise I had a lot of spatter.
Pipe Contractor Eliminates Back Purge on Stainless Steel Pipe
2020年12月8日 · For welding stainless steel pipe, Dixie Mechanical followed the traditional process of using a TIG root pass with an argon back purge followed by flux-cored fill and cap passes. The back purge on stainless steel was an especially time-consuming process, typically requiring 20 to 30 minutes depending on the pipe size to set up the argon ...
Pulsed TIG Helps Reduce Costs and Increase Productivity When …
2007年11月2日 · H.L. Lyons Company, a manufacturer of stainless steel appliance components, switched to high-speed TIG pulsed welding with new TIG welders. By increasing pulsing rates from 10 PPS up to 175 PPS, the company cut welding time by up to 50% and reduced finishing time (post-weld grinding) by one-third.
Regulated Metal Deposition (RMD™) MIG Welding Process ... - Miller
2008年3月2日 · The techniques for welding carbon steel pipe are the same as those described here for welding stainless. However, to qualify procedures for welding 300 series stainless steel pipe without backing gas, fabricators must do the following: Ensure a minimum 1/8-in. gap around the entire circumference of the joint.
Welding stainless to mild steel - Miller Welding Discussion Forums
After reading these posts I decided to weld it up with 308 filler (all the stainless-stainless pieces) and then autogenous welded the mild steel to stainless around the inside of the flange. On the outside I put three evenly spaced 1/2" long welds using 308 filler.
