Stainless steel pipe fitting welding machine

The invention relates to the technical field of welding machining, and particularly provides a stainless steel pipe fitting welding machine. The stainless steel pipe fitting welding machine comprises a base, an outer clamping and positioning mechanism used for clamping and positioning a flange plate, an inner supporting and aligning mechanism used for inner supporting and positioning of a stainless steel pipe fitting, a rotary welding mechanism and a bearing and pressing mechanism fixed to the base. According to the welding machine, automatic rotary welding machining can be carried out on the flange plate and the stainless steel pipe fitting which are different in matching size, traditional manual welding is replaced, the welding machining efficiency is greatly improved, the influence of manual factors on the welding quality is eliminated, and the welding quality is guaranteed. 本发明涉及焊接加工技术领域，具体提出了一种不锈钢管件焊接机，包括底座、用于法兰盘夹紧定位的外夹定位机构、用于不锈钢管件内撑定位的内撑对正机构、回转焊接机构和固定在所述底座上的承托压紧机构；该焊接机能够针对不同配合尺寸的法兰盘与不锈钢管件进行自动回转焊接加工，代替了传
