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.
The Big Debate South Africa is a South African television debate series with a focus on pertinent contemporary political topics to South Africa.

The primary chemical reaction involves the acetylene disassociating in the presence of oxygen to produce heat, carbon monoxide, and hydrogen gas: C 2 H 2 + O 2 → 2CO + H 2. A secondary reaction follows where the carbon monoxide and hydrogen combine with more oxygen to produce carbon dioxide and water vapor.

The efficiency is dependent on the welding process used, with shielded metal arc welding having a value of 0.75, gas metal arc welding and submerged arc welding, 0.9, and gas tungsten arc welding, 0.8. [64] Methods of alleviating the stresses and brittleness created in the HAZ include stress relieving and tempering. [65]
She jumped into the race after three other Democrats failed to earn enough votes to make it past the Aug. 6 primary election. Instead, voters chose to back Newhouse and Sessler — both ...
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: no minimum content is specified or required for chromium , cobalt , molybdenum , nickel , niobium , titanium , tungsten , vanadium , zirconium , or any other element to ...
