This will help maintain their alignment and prevent twisting while the final weld is being applied. 4. Weld sequence: Adopt a strategic weld sequence that minimizes heat distortion and potential twisting. Avoid welding a continuous bead along the entire length of the flat bars, as this can generate excessive heat and cause distortion. Instead, alternate between different sections or weld in short intervals, allowing each area to cool before proceeding. 5. Minimize heat input: Control the heat input during welding by using the appropriate welding technique and adjusting the welding parameters. High heat levels can cause the steel to expand and contract, leading to twisting. Employing techniques such as pulse welding or reducing the amperage can help control heat input and minimize the risk of twisting. 6. Preheating and post-weld heat treatment: For thicker or more susceptible steel flat bars, preheating the material before welding can help reduce the risk of twisting. Additionally, performing post-weld heat treatment can relieve residual stresses and prevent distortion. 7. Slow cooling: Allow the welded flat bars to cool slowly and naturally after welding. Rapid cooling, such as through water quenching, can induce additional stresses and contribute to twisting. Avoid abrupt temperature changes and provide adequate time for the welded bars to cool down gradually.
