FIELD: mechanical engineering; repair and reconditioning of parts exposed to cyclic thermomechanical loads. SUBSTANCE: welded on section consists of two layers in height: inner donor layer made of high alloyed steel and outer, wear-resistant layer made of alloyed steel. Summary content of alloying ...
摘要: PROBLEM TO BE SOLVED: To provide a method for two-dimensional analysis of welding deformation and a residual stress which attains sharp reduction of the time for analysis and enables highly accurate analysis of the welding deformation and the residual stress....

Mechanical fasteningand even adhesive bonding might be suitable methods, especially if intended as a temporary solution until spare parts are obtained. To decide on the material type involved,x-ray fluorescence(XRF) is the suggested qualitative method because it is immediate and non destructive. It ...

method used toshieldthe weld from the atmosphere. InTable 6.1, which sets out the characteristics of the more important fusionwelding processes, the method of shielding has been used (arbitrarily) as a means of grouping the different methods. The first group is that employing slag, or a ...
A prerequisite for a successful result is properly managed process control, in order to avoidweld defects. The welding heads are of special design, with precision mechanical control. Narrow-gap welding is used primarily for MIG/MAG, TIG and submergedarc welding. ...
This article presents a novel method of thermite welding. A hand operated portable welding can be conveniently realised using self-made thermite welding pencil without any welding equipments. A butt junction was obtained between two low carbon steel plates. Morphological, microstructure and mechanical an...
Submerged arc welding (SAW) (Figure 10.1), is a high-productivity method of welding, generally carried out using mechanical welding methods and suitable for use with 1–3 continuous wire electrodes. Sign in to download full-size image Figure 10.1. Schematic diagram of submerged arc welding. The...
