Introduction to Welding (4 Parts)
- Synopsis
- Live-action videos providing for each topic: definitions, welding components, safety equipment, assembly and use of the system, the types and kinds of welds. Safety procedures are emphasised throughout, including the proper clothing, equipment and filter lens required for the work.
1 (1998): Explains and demonstrates the careful and safe method of using the combination of acetylene and oxygen gas cylinders. Demonstrates pressure regulators, check valves, hoses and fittings, torch tubes and tips. Explains ignition, use and shutting down and presents tips on the flame adjustment and methods to direct it to the work area. Also demonstrats various welding techniques and types of weld.
2 (1997): Explains the differences between the alternating current and direct current arc welding machines and shows how an electrical current melts electrodes to supply filler metal. Demonstrates electrode leads, workpiece leads and electrode holders. Explains electrode sizing and its importance, and gives step-by-step instructions for set-up and shut-off. Discusses and demonstrates uses of the shielded metal arc welding process.
3 (1998): Gas tungsten arc welding (TIG) presents special safety concerns. Viewers are warned of the suffocation hazards present when working with inert gases and told why good ventilation is required. Also explains how TIG welding differs from other types of welding, in particular the use of non-consumable electrodes. Explains and demonstrates electrode leads, hoses, regulators, collets, and the use of the post flow timer to protect the weld from contamination. Also discusses use of the correct collet set and electrode size and type needed for the job.
4 (19978): Explains similarities between gas metal arc welding (MIG) and flux core arc welding, including the use of direct current to provide constant voltage. Shows the different kinds of wires used in each. Demonstrates wire feeders and the spools that feed them, allowing welders to make long continuous welds. Demonstrates how to position the electrode and how to establish a good weld pool. - Language
