Abstract

A method for welding the frame of a low speed diesel engine. It includes the following steps: 1) By passing locating iron pipes through the screw holes in small iron plates, a number of small iron paltes are located between two bed-jigs according to the requirements of design, and spot welded on a guide plate and a triangle plate to form guide plate components. 2) The bilateral symmetric and located guide plate components are put symmetrically side by side and located by butt strap welding. 3) The welded and located bilateral guide plate component are welded in symmetry. 4) After welding, butt straps are removed, and the bila-teral guide plate components are separated. 5) with the help of the bed-jig, the bilateral guide plate components and a division plate are located on a cast-iron platform.

Description

Technical field: [0001] The invention relates to a low-speed diesel engine and relates to a welding method, in particular to a welding method for a frame of a low-speed diesel engine. Background technique: [0002] The local space of the diesel engine frame is small, but the requirements for the welding seam are high, welding and cleaning are difficult, and the welding deformation is difficult to control. The welding process of the existing diesel engine frame is as follows: Figure 7 and Figure 8 as shown, Figure 7 It is a schematic diagram of existing symmetrical groove welding. After welding 1-2 layers on the front side, and then welding on the back side, carbon planing must be carried out before welding, so that the actual welding position on the back side exceeds the center line, resulting in asymmetric deformation. It is difficult to control the deformation. Therefore, the amount of deformation does not meet the specified requirements. [0003] Figure 8 Is the sc...
