There are several common welding techniques that can be used for steel angles:
1. Stick welding, also known as Shielded Metal Arc Welding (SMAW), is a popular choice. It involves using a consumable electrode coated in flux, which creates a protective shield around the weld pool. SMAW is versatile and can be used for steel angles of various thicknesses.
2. Gas Metal Arc Welding (GMAW), also known as MIG welding, is another technique that uses a continuous wire electrode and a shielding gas, typically a mixture of argon and carbon dioxide. GMAW allows for high welding speeds and provides good control over the weld pool, making it suitable for steel angles.
3. Flux-Cored Arc Welding (FCAW) is similar to GMAW, but instead of a shielding gas, it utilizes a flux-filled wire. When heated, the flux creates a protective gas shield that prevents contamination of the weld. FCAW is especially useful for outdoor welding or in windy conditions.
4. Gas Tungsten Arc Welding (GTAW), also known as TIG welding, is a precise and clean welding process. It uses a non-consumable tungsten electrode and a shielding gas, usually argon. GTAW produces high-quality welds on steel angles, making it a preferred choice for thin angles or when aesthetics and control are important.
5. Submerged Arc Welding (SAW) is a semi-automatic or automatic welding process that involves feeding a continuous wire electrode and a granular flux into the weld zone. The flux covers the weld, preventing atmospheric contamination. SAW is commonly used for thicker steel angles and provides high deposition rates.
It is crucial to select the appropriate welding technique based on the specific requirements of the steel angle joint, such as thickness, joint design, and desired weld quality. Additionally, proper preparation, including cleaning and preheating if necessary, is essential to ensure successful welds on steel angles.
