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.
Processes that employ inert gases to protect the weld cannot be readily used in such situations, because unpredictable atmospheric movements can result in a faulty weld. Shielded metal arc welding is also often used in underwater welding in the construction and repair of ships, offshore platforms, and pipelines, but others, such as flux cored ...

The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...
Among the construction trades, in most industrialized countries, each has a distinct 2-5 year craft apprenticeship education and usually once started a worker remains in a single craft and progresses through ranks of skill for the duration of their career (pre-apprentice, apprentice, and journeyman; some countries include a post-journeyman ...
What's more, the median pay for new construction hires was $48,089 last year, compared to $39,520 for professional services new hires, according to data from payroll services provider ADP.
