Spray Arc Welding – A welding process by which molten material is transferred in the form of many small droplets, the diameter of which is less than that of the filler wire. Stabilized Stainless Steel – A high-chromium steel that does not lose its chromium from solid solution by precipitation, because of the addition of elements that have a greater attraction for carbon than does chromium.

When MIG welding aluminum, obtaining good quality and productivity depends on using the right welding process and system. The newest generation of pulsed MIG welding systems address the differences between aluminum and steel, and generally provide a quick return on investment through increased productivity, reduced downtime and better weld quality.

Ideal for welding nonferrous metals, Emerson ultrasonic metal welding systems meet the production demands of consumer brands and OEMs in the automotive, HVAC and electronics industries. The energy efficient-processes eliminate the need for added materials or contaminants such as flux agents, solder, solvents or crimp connectors, reducing materials costs.
An additional wire control keeps the current and penetration constant if the distance between the welding torch and the component changes. The arc becomes significantly more stable and the penetration is much more constant.
Quality Assurance Quality Assurance (QA) is a set of defined processes for systematic monitoring and evaluation to assure product quality. Quality Control Quality Control (QC) is the process of confirming that the product meets the specifiions. It includes the checking and testing of manufacturing procedures as well as the final products. The results from these […]
Work angle: With wire welding, hold the gun at a 10 to 15 angle into the direction you are pushing the weld. With stick welding, maintain a 20 to 30 lead angle in the dragging direction. With a fillet (tee) weld, hold the rod or wire (regardless of weld process) at
In CO2 arc welding of solid wire, metal transfer phenomena and spatter generation are investigated with rectangular pulse current, and a low spatter CO2 arc welding process with high frequency
Welding operators can also determine whether the drive rolls are the problem through a process of elimination. Namely, by conducting a “two finger” test — disengage the drive rolls, grasp the welding wire and pull it through the gun. It should be able to pull easily
Solid wire, when used with knurled drive rolls, will not change shape like flux-cored wire, but will develop the “teeth,” and similar wear. Solution: Periodically, before feeding the wire through the cable/hose assely, use an air nozzle and shop air pressure to blow out the liner, first from the torch end and then, if convenient, from the feeder end.
What is submerged arc welding (SAW) process? As one of the many arc welding methods, submerged arc welding is for the joint of butt welding, fillet welding, lap welding. Maintained between the tip of wire and base metal, a stable arc is under the cover of granular agglomerated flux or fused flux.
8. Chips on the lips No, we''re not talking about lunch. We''re talking about chipping occurring on the lips of your drill bit - basically your jobber drill is breaking down. How is this happening? Too much lip clearance (over 15 ) will cause cutting lips to break down - re-point/sharpen or replace the drill.
Welding thicker pieces of Aluminum 1/4 inch to 1/2 inch then you may well find a mix of Argon and Helium better for deeper penetration. Typically 25% to 75% Helium is used but check the data sheet of the welding wire you plan to use and what mix the
When not in use, protect spools of wire by covering them on the wire feeder, or better yet, remove the spool and place it in a clean plastic bag, closing it securely. As with any welding process, it takes time and practice to gain the best performance when MIG
30/10/2019· Welding is the process of using electrical current to superheat and melt metal so that you can join two pieces of metal together. There are several ways to weld, but the two most popular ways to weld at home include gas metal arc welding, or MIG welding, and arc
27/2/2020· Welding is a way to coine pieces of stainless steel together for repair work and even craft projects. To begin a weld, set the steel in place over a welding table using clamps and jigs. Then, join the steel together through MIG or TIG welding. MIG welding is an
Wire should be stored at aient conditions of temperature and humidity, and dusty areas should be avoided when wire is not enclosed in some type of dust-protecting container. Cut-length wire used for GTAW welding should be protect-ed from dust and
3/9/2009· Welding at high voltages, especially with an electrode or welding wire that creates a particularly fluid weld pool can also cause the resulting weld bead to be more concave. This again reduces the throat thickness and weld strength, making it more prone to bead shape cracking.
Ultrasonic welding is a widely recognized and accepted process for joining thermoplastic materials. It offers many advantages, including process reliability and repeatability, lower energy usage than other joining techniques, material savings (because there is no need for consumables, such as glue or mechanical fasteners), and labor savings.
