Husky is a line of hand tools, pneumatic tools, and tool storage products. Though founded in 1924, it is now best known as the house brand of The Home Depot, where it is exclusively sold. Its hand tools are manufactured for Home Depot by Western Forge, Apex Tool Group, and Iron Bridge Tools. [1] Its slogan is "The toughest name in tools."
Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).
Quality requirements of welded joints depend on the form of application, e.g. in the space or fly industry weld errors are not allowed. [1] Science try to gets good quality welds. There are many scientific articles describing the weld test, e.g. hardness, [2] [3] [4] tensile tests. [3]
Welder certification is based on specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The main part of the welder's test consists of welding one or more test coupons which are then examined using non-destructive and destructive methods. The extent of certification is described by a number of variables ...
The weldability, also known as joinability, [1] of a material refers to its ability to be welded. Many metals and thermoplastics can be welded, but some are easier to weld than others (see Rheological weldability). A material's weldability is used to determine the welding process and to compare the final weld quality to other materials.
In the scan images, the good weld appeared as a uniform line. The defective welds exhibited various discontinuities and a non-uniform appearance. Mechanical testing of the welds showed a marked decrease in properties, with reductions in the yield stress of one-third to one-half the value of the good weld.
