Advantages and Disadvantages of Welding
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal,
- The generally cost of welding equipment is commonly low.
- Relative simplicity and portability of equipment.
- Many portable welding instruments are available.
- A large number of metals can be welded.
- A good weld is as strong as base metal.
- Welding can mechanized for assembly.
- It produces a permanent joint.
- As welding produces inside stresses, the work piece often require annealing or stress-relieving.
- Welding gives off dangerous radiations similar to light, fumes and spatters.
- Capable welder is necessary for performing a good welding process.
- Welding make lasting stresses and distortion in workpieces.
- Welding create structural, physical, and chemical changes.
- Edging preparation is commonly necessary before welding.
- Jigs and fixtures are desirable to hold parts in place.
