Welding is a process of joining in which two or more pieces of metal are combined at their contacting surfaces by applying heat and/or pressure. It is an increasingly high-technology skill. Large number of welding processes are achieved by welding rather than pressure. While others maybe accomplished by both heat and pressure. These are also few process that need only pressure without any external heat. Some joining techniques, use filler material that is added to facilitate joining. Before knowing advantages and uses of metal fabrication, here are some disadvantages that are given below: often, metal joining processes are performed manually and are extremely expensive in terms of labor costs, some metal combining methods are dangerous and also they use high energy, joints may have quality defects that may difficult to detect. To perform excellent welding task, experienced manpower and quality welding equipments are the paramount requirement.
TIG welders are the equipments used for tungsten inert gas welding. In this kind of welding, non-consumable tungsten electrode is used. This electrode provides an electric arc. Electrode, area of welding and arc is shielded by a sheath of inert gas. This shielding process prevents any oxidization of the weld and produces a neat and clean weld. This technique is slower than MIG. In some cases, Tig is used in conjunction with metal inert gas welding. Applications of Tig include vessels, pipe work, nuclear and petrochemical industries. It is used in various kinds of alloys like aluminum, titanium and magnesium fabrications for aerospace industries and also in bicycle and motorcycle frames, beverages and food industries. This kind of joining technique is becoming highly critical for transportation industries, as vehicles like cars, trucks, aircraft are made lighter to reduce fuel consumption.
Plasma can be defined as a high temperature, electrically conductive gas, consist of negatively and positively charged particles. It is a thermal cutting technique in which arc is fasten through a nozzle. Make your task of cutting metals convenient and short with high quality plasma cutters. It works like a hot knife through butter. They help to give superb shape and cut to metals. Large number of industries depends upon the manipulation of alloys and metals. Metals are needed to build tools, robots, cranes, bridges, cars, skyscrapers, other heavy transportation that are necessary in day-to-day businesses. The reason behind extreme use of metals is that they are extremely durable and strong. To cut these strong metals to give them a particular shape, plasma machines are developed. Equipments needed for Plasma cutting are: Power source, Burner electrode and nozzle, Gas supply, Workpiece, Coolant circulation system, cutting bench, exhaust system.
To improve your efficiency to cut metals, there are some points to consider: read the manual properly for the safe and correct use of plasma cutter. In this way, you can take advantage of your cutting machine's capabilities. Make a sample cut on the similar metal that you are going to use for your project. It is difficult to continue for long cuts. You can practice your movements to make sure yourself to make a clean continuous cut.
