The ethernet technology is used in multi-arc submerged arc welding systems communicate with each other. The structure of twin-arc high-speed SAW (Submerged arc welding) equipments based on Ethernet is proposed. The welding equipment technical requirement for Ethernet is discussed. The crucial implementations of Ethernet TCP / IP in the welding equipment is presented including designs of ARM (Ad...

This paper focuses on Friction Stir Welding (FSW), a fairly recent technique, invented by The Welding Institute (TWI) in 1991, that utilizes a non-consumable rotating welding tool to generate frictional heat and plastic deformation at the welding location; thereby, affecting the formation of a joint while the material is in the solid state. In particular, FSW can be used to join high-strength a...

1. Numerical calculations have been performed with the use of PLGrid Infrastructure. This work was supported in part by National Science Centre (Poland) under grant no: 2016/21/B/ST8/00462.

Welding of metals and alloys is important to Dentistry for fabrication of dental prostheses. Several methods of soldering metals and alloys are currently used. The purpose of this study was to assess, using the flexural strength testing, the efficacy of two processes Nd:YAG laser and TIG (tungsten inert gas) for welding of pure Ti, Co-Cr and Ni-Cr alloys. Sixty cylindrical specimens were prepar...

Welding-related asthma is well recognised but less is known about rhinitis in relation to welding. The aim here, was to study associations between welding, rhinitis and asthma in a general population sample, and factors influencing selection into and out of a welding occupation.Adult-onset asthma and non-infectious rhinitis were investigated in the international multicentre population-based Res...

Experimental study was conducted to assess personal welding fumes exposure toward welders during an aluminum metal inert gas (MIG) process. The welding process was carried out by a welding machine attached to a Computer Numerical Control (CNC) workbench. A dummy welder was used to replicate welder during welding works and was attached with sampling pumps and filter cassettes for welding fumes s...

A prototype of autonomous mobile robot with two vision sensors for automatic welding of steel plates was constructed. The robot can move straight, steer and turn around the robot center by controlling the driving speed of the two wheels respectively. At the tip of the movable arm, two CCD cameras are fixed. A local camera observes the welding line near the welding torch and another wide camera ...

Since the control system of the welding gun pose in whole‐position welding is complicated and nonlinear, an intelligent control system of welding gun pose for a pipeline welding robot based on an improved radial basis function neural network (IRBFNN) and expert system (ES) is presented in this paper. The structure of the IRBFNN is constructed and the improved genetic algorithm is a...
