Title: SEAMLESS COMPLETELY WELDED WINDOW AND PROCESSING METHOD
Abstract:
Disclosed is a seamless completely welded window. The window comprises a transverse frame (1) and a vertical frame (2), wherein the transverse frame (1) and the vertical frame (2) form a window frame structure by intersplicing of section bars and by seamless welding, and a corner angle at the splicing location of the transverse frame (1) and the vertical frame (2) is a rounded angle having a radius of 3 mm to 15 mm. Also disclosed is a processing method for a seamless welded window. The processing steps are as follow: A, performing, according to set length dimensions of section bars for the transverse frame (1) and the vertical frame (2), section bar cutting, and cutting out splicing surfaces at end faces of the section bars of the transverse frame (1) and the vertical frame (2); B, splicing the transverse frame (1) and the vertical frame (2) into a window frame along the splicing surfaces and welding the same to form a welding seam along the splicing surfaces; and C, polishing the seam, then performing rounding-off processing on a corner angle of the window frame, and performing spray coating on the window frame as a whole. A rounded angle structure design of the seamless completely welded window according to the present invention can avoid injuries due to the presence of sharp edges and improve user safety. The seamlessly welded structure can eliminate joint seams in a window frame, thereby achieving good leakproof properties and preventing rainwater corrosion.
