► Precautions for specific welding and cutting situations;
► Actions to correct distortion after welding.
The system also includes a series of quiz type questions that will test
the user's understanding of distortion.
Simulation
MAGSIM simulates the GMA welding process calculating the weld
shape and the thermal cycle at various points along the weld (7). Graphics is
used to display the cross section of the weld and a 3-D view is used to
visualize the simulation results; the calculated thermal cycle and shape of
the weld pool. The program can be used to predict the weld quality for
selected welding parameters with tolerances. For butt and fillet joints in
СMn and alloy steels, welding parameters can be optimized for a specific
task.
Education and Training
WELDING FUME TUTOR is a CD ROM based multimedia training
course aimed at educating welders, supervisors and welding engineers on
the risks to health that could arise from inhalation of welding fume. The
program can also be used for training welders in fume control techniques
and use of extraction equipment. The information contained is based on
statutory regulations, expert knowledge and practical experience. The
program is interactive and combines video clips, animated sequences, audio,
scanned photographs and graphics.
Welding engineering IT and the Internet
The Internet is unique in that it contains a vast store of information
which is readily available to engineers 24 hours a day. Its potential as a
source of IT for welding engineers has yet to be fully realized. In order to
realize this potential, welding engineers must have knowledge of:
► The Internet System;
► World Wide Web (WWW)
► Hardware Requirements
► Accessing and Searching the WWW
The Internet System
The Internet is not a single computer but a network of millions of
computers linked by a telecommunication system (copper wires, fibre optic
cable and satellites). In simple terms, the Internet can be considered a
world-wide array of computer networks linked by the telephone.
