01. Welding type sum special point
Welding and finger passing heating or pressing, use two or more separated parts, passing atomic combination formation, and connecting method. Commonly used laser cutting method Yes melting, pressure welding Japanese .
Welding method phase ratio, welding advantage points, welding points, and welding points.
Opposite other connection method, welding advantage: Welding phase ratio, Welding material, High efficiency, Welding sealing property; , Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding, Welding.
Naturally, the point of welding is easy: easy welding, welding, and welding, and welding, and welding, and welding, and so on.
02. Welding and welding
Triggered arc: General work case Japanese electric pole division separate connection arrival The best possible contact and electrical source. At the time of the other momentary contact, the medium-sized medium-produced medium-sized electric discharge, the name of the electric contact arc.
Arc-like composition: Electric arc Yusan sub-composition, Immediate cathode zone (occupancy 43%), Cathode zone (occupation 36%) Japanese arc pillar zone (occupation 21%).
Welding process: Three main parts of the welding process: Welding zone formation; Heat-affected zone formation; Welding crystal Japanese welding formation.
Main measures in terms of quantity and quantity: (1) Welding area; (2) Easy-to-burn alloy element in the welding pond; (3) De-o, P, s in the welding pond.
Electrode Yushin Japanese plating. Welding core, with constant diameter, total length, special lead, economic special welding, main lead, Japanese product, live contact, current action; Actions such as welding and conditioning chemical components.
03. Conventional contact method
Commonly used welding method Air-welded welding, buried arc welding, electroslag welding, electroslag welding.
Gas body protection electric arc (GMAW) One type of use External gas body operation electric arc Welding electric arc Japanese welding method. Welding of carbon dioxide and welding of carbon dioxide.
CO2 welding gas body, welding method. Advantages: High productivity, high speed of Hiteko electric arc welding 1-4 times; good welding quality; good operation performance, easy inspection open arc; low quality book. The point: CO2 easy decomposition at high temperature, CO sum o, easy redox decomposition, CO impossible separation, formation stomata, leading stomata.
04. Welding of ordinary materials
Metallic material example, metallic material flammability: Under constant welding conditions, the prefix is welded.
Material fertility measurement index: Molded welding sensitivity; use performance (machine performance).
Shadow Welding Sexual Factors: Metallic Material Welding Material; Welding Method, Welding Material Welding Welding
Other material-based welding, carbon-steel welding, low-alloy-structured welding, non-carbon steel welding, steel-based welding, colored metallic welding, non-conformity welding.
