svetsfog

A svetsfog, or weld joint, is the area where two or more metal pieces are joined together by welding. This joining process involves melting the base metals along with a filler material to create a continuous bond upon cooling. The strength and integrity of the svetsfog are crucial for the overall performance and safety of the fabricated structure.

There are various types of svetsfog, classified based on the relative position of the parts being joined. Common types include butt joints, where the edges of the metal pieces are aligned and joined; lap joints, where one piece overlaps another; T-joints, where one piece is perpendicular to another, forming a T-shape; corner joints, where two pieces are joined at an angle, typically 90 degrees; and edge joints, where the edges of two parallel or nearly parallel pieces are joined.

The design and preparation of the svetsfog significantly influence the welding process and the final joint quality. Factors such as the type of weld, joint preparation (e.g., beveling), selection of welding consumables, and welding parameters (e.g., current, voltage, speed) are all critical. Proper inspection and testing of the svetsfog are often performed to ensure it meets required standards and specifications, which can include visual inspection, non-destructive testing (NDT) like radiography or ultrasonic testing, and destructive testing. The term svetsfog is commonly used in Swedish.
