Due to the welding characteristics of titanium alloy itself and the complexity of welding structure in high-speed rail bogie

how to ensure the welding quality and size requirements in the welding process has become the biggest difficulty in the production and manufacture of titanium alloy high-speed rail bogies. Especially the bogie frame

as the important working procedure of the welding of the bogie

the guarantee of its quality and accuracy is the key to follow-up production of the bogie. By compiling reasonable welding process rules

we have effective regulations on the preparation before welding

the sequence of pairing

the welding sequence

the requirements of welding parameters

the preparation of tooling and the requirements of heat treatment

etc

so as to improve the welding quality and size requirements of the bogie frame. Through the actual welding of the bogie side beam on the spot

the weld quality after welding meets the requirements

and the side beam size meets the requirements of the bogie pairing.
