Types of welding deformation of steel structure and flame correction:
The main components of steel structure are welded H-steel column, beam and brace. The following three flame correction methods are often used for welding deformation:
(1) Linear heating method;
(2) Point heating method;
(3) Triangle heating method.
The following describes the construction methods to solve different parts.
The following is the heating temperature for flame correction (made of low carbon steel)
Low temperature correction (500 ~ 600 ℃): cooling mode: water
Medium temperature correction (600 ~ 700 ℃): cooling mode: air and water
High temperature correction (700 ~ 800 ℃): cooling mode: air
