Determination of preheating temperature and heat treatment temperature before welding

Date:2019-08-27View:964Tags:Determination of preheating temperature and heat treatment temperature before welding
he preheating temperature of ordinary carbon steel and low alloy steel is determined according to the range of carbon equivalent before welding.

the range of carbon equivalent %            preheating temperature ℃

CE<0.45                                                          Not preheat 

0.45≤CE<0.6                                                   100 - 200

CE≥0.6                                                              200 - 370


Commonly used steel after welding stress relief heat treatment temperature.

Material     Carbon steel&medium and low alloy steel   Austenitic steel   Aluminum alloy   Magnesium alloy   Titanium alloy   Cast iron

℃                                     580 - 680                               850 - 1050           250 - 300               250 - 300              350 - 600      600 - 650
