TIG welding stands for tungsten inert gas welding. It is the procedure of blending together metals that are reactive, such as both aluminum and magnesium. This kind of welding started to be really popular back in the 1940s, and it helped to establish the utilization of aluminum for welding and structural needs. The following TIG welding tips will help you improve your TIG welding quality.
One of the keys to TIG welding tips is understanding how you should prepare your weld joint. First, you ought to clean both the filler metal as well as the weld joint area. This demands that you remove all dirt, grease, paint and oil. A contaminated weld or arc instability might be the result of failing to clean the weld joint properly. For added safety, you should also look into a clamp, which may be needed if you fail to support your work piece during the welding process. Weld joint preparation also calls for creating one-quarter inch tack welds right along the work pieces so that they do not separate.
Many TIG welding tips focus on how to position your TIG torch if you are faced with various kinds of joints.
For example, if you are confronted with a butt joint, you should focus the weld poll onto its adjoining edges. After finished with welding, you are advised to lower the heat or amperage to help in filling in the crater.
If you are faced with a lap joint, shape the weld pool so the flat surface of the second piece and the edges of the overlapping piece flow together nicely. Because the edge has a tendency to melt quicker, dip the filler rod right beside the edge while also making certain that you are utilizing sufficient filler metal to finish the joint.
You can ask your co-workers about TIG welding tips that address the T-joint. When welding one, the flat surface and the edge must be joined together so that the edge will melt quicker. Be sure to also angle your torch to point greater heat towards the flat surface and lengthen the electrode past the cup in order to hold a shorter arc. Place the filler rod at the point the edge is melting.
The final tip on TIG positioning relates to the corner joint. Both edges of any adjoining pieces must be melted. The weld pool has to be kept on the centerline of the joint. Since a convex bead is required for this kind of joint, an adequate amount of filler metal should be provided.
The above TIG welding tips are basic, but they help ensure that you have a greater chance at succeeding at this type of welding. Proper TIG welding comes down to first preparing your weld joints in the right manner. First of all, this involves being very meticulous in cleaning away all the dirt, oil, greases and paints. Clamps and tack welds are also integral aspects of preparing your weld joints in the right way. One of the biggest factors in welding is positioning your torch just in the correct manner to do the job right. In TIG welding, you will encounter four, main types of joints: the butt joint, the lap joint, the T-joint and the corner joint. Knowing how to hold your torch properly in these situations is essential.
