The job of a welder is not for the faint of heart. They usually must work outside, in all sorts of weather, and sometimes are exposed to hazardous working conditions.
From working inside pipes, to going underground, to scaling the tops of bridges and buildings, welders are faced with a unique set of challenges each day. They also typically work overtime often, as you cannot really leave a job half-finished in this line of work. MIG welding uses a gas metal arc to fuse steel or aluminum and is the most common type of welding. TIG uses tungsten inert gas for its fusion and is used when a high-quality weld is required.
Arc welding is often used in private homes and offers a basic fusion. It is also known as stick welding. Understanding these differences in welding techniques is all part of the job.
As long as you have the interest and the tough-mindedness, becoming a welder is not very difficult. Lifting gear for transporting and turning parts Work platforms Turning devices or manipulators to facilitate welding in the flat position. Clamping devices for welding assemblies Devices for straightening Protection when working with aluminium or stainless steel to keep away dust, spatter, gases and fumes which might reduce the corrosion resistance of the parent metal or the quality of weld.
The following items, in particular should be specified and described. For welds which are classified in the weld performance class CP D, a welding procedure specification is necessary only if it is demanded by the customer. Open navigation menu. Close suggestions Search Search.

Current status and future aspects of FSW:. Current status of friction stir welding: By availing this process, hard materials like steel and other vital engineering alloys can be efficiently welded. It decreases defects and enhances uniformity of weld properties.
It also expands applicability of friction stir welding to modern engineering alloys. Future aspects of friction stir welding: It includes analyzing the influence of processing parameters on welding stages, plunging, and transition.
Future work also includes analyses of non-heat treatable aluminum series and heat treatable aluminum. It is a demand of aircraft industries to substitute conventional joining applied sciences with frictional stir welding which is affordable and highly efficient.
