If you grind your electrode on a wheel that is shared by steel, you run the risk of embedding contaminants in the tungsten. Now, just as you would normally grind your tungsten (always leaving the grains from grinding, lengthwise) and making the length of the pointed cone about 2x the diameter of the electrode. Remember to nip the tip off the pointed cone so it doesn't blow off into the weld ...

Weld joint and quality. Except for some special base materials, the strength of weld joints is considered to be the same as that of the base materials. There are many different types of weld joints based on the style of joining base materials. The strength of welding depends on which parts of the base materials are welded and how.
Setting up your welding shop is really about logic more than technical know how. Those new to welding are quick to forget about the extreme temperatures needed within a welding process and as such never realize the fire hazard of your welding area. Should you be wellversed, it really is fairly obvious that carpet in the welding shop is not ...
Groove Welds. Use a plasma cutter or a grinder to create beveled edges on thicker materials measuring more than 3/16″, while you can stick with a square groove weld for thinner metals. Basic Groove Welds. Whether you're doing square groove welds or Vgroove welds, keep the electrode at right angles to the metal, but lean it in the direction that you're welding. If you tilt it in any ...
· If you notice a brownish oxidation or flakes that look like black pepper in your weld puddle (Figure 2C), decrease the balance setting which will increase the time in EP or the time spent in the "cleaning action." However, note that too much EP causes the tungsten to ball excessively (Figure 2D) and could provide too much etching. Lastly, when TIG welding aluminum, do not start welding until ...

· The secondmost popular carbide pattern is a 6weld side with carbide applied down the side of the tip/insert as well to protect the tip and hammer from wear. 4weld with corners/buttons . Swing hammers generally have carbide applied only across the tip and down the sides but, as long as you have clearance in your machine, you can put carbide almost anywhere to meet your specific tub or ...
· One of those factors is the requirement that the weld joint needs to be able to physically accommodate the chosen welding process and any accompanying welding equipment (nozzles, torches, etc.). Consider the case where the joint design incorporates a bevel (on at least one side of the joint) and a root opening. Two examples of AWS prequalified joint designs with this type of preparation ...

· Removal of rust, crosscontamination, and heat tints – If rust has already appeared on your weld, ... grinding is often overly laborious and can cause significant noise and air pollution. However, the biggest concern is the lack of surface repassivation. Sure, you can use abrasive discs to successfully remove rust and other contaminants from the surface. However, when it comes to stainless ...
A welder needs to be able to interpret welding symbols to insure he puts down the right kind of weld, that he prepares the joint properly, that he places the weld in the right spot, right sequence, right dimension, etc. A design engineer needs to know the symbols to communie this clearly to the welders and supervisors. A project manager will need to know this when bidding a job. The welding ...

To really test a weld you need to do a xray test, magnaflux test, dye penetrant test or ultrasonic test which looks for voids, lack of fusion, etc. Welds are typically quality tested based on the function for which is intended and under conditions that are the same or more severe than those encountered by the welded structures in the field.
