Part 1 Part 2 Part 4 Part 5. Fillet welds may be combined with full or partial penetration butt welds - a combination weld. The designer is therefore required to decide whether to use a T-butt weld, a fillet weld or a combination of the two. In making this decision cost is a major factor. As mentioned in Job knowledge 91, the fillet weld requires no weld preparation, is easy to deposit and is often regarded as the cheapest weld of all to make.

A large part of the lecture deals with the actual stress distribution and the deformability of fillet and butt welds.
Welding is a core activity in the fabrication factory, undertaken by skilled, qualified operatives working to a welding quality management system under the control of a Responsible Welding Coordinator. It is used to prepare joints for connection in the shop and on site, and for the attachment of other fixtures and fittings. Different welding techniques are used for different activities within the fabrication factory.
Butt welding is a commonly used technique in welding that can either be automated or done by hand on steel pieces. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. To achieve this the heat input is controlled, which decreases the size of the weld. Butt welding is best performed with MIG or TIG welding applications due to their natural ability to connect two pieces of metal together. For the heavily coated electrodes are commonly used in structural welding because they are much stronger and corrosion resistant.
