2. Selection of welding wire and flux
(1) The welding wire is mainly selected as the filler metal to add alloy elements to the weld and directly participate in the metallurgical reaction in the welding process. Its chemical composition and physical properties not only affect the stability in the welding process, the performance and quality of the welding joint, but also affect the welding production rate.

In mature industries, pneumatic butterfly valve manufacturers and enterprises often successfully reduce product prices to the level of market leaders through low-cost inputs. Due to inertia or unionization of employees, the cost of old enterprises is generally high. In the past 20 to 30 years, the market share of American pneumatic butterfly valve manufacturers and enterprises has declined significantly, which is the result of collective agreements on wages, benefits and work system at a considerable level. In the 1970s and 1980s, overseas steel enterprises and domestic small steel enterprises gained strong competitiveness from low wage labor, and wantonly absorbed the market share of these large enterprises. New market entrants can also purchase factories and consumer equipment at low prices, thus gaining cost advantages in mature industries.
