Medium structural welds usually require one to two days, while large projects like bridges can span weeks or months. Calculate welding time from weld length and speed, estimate heat input from voltage and current, and total arc time for multi-pass jobs and batches. The following formula is used to calculate the welding time. For example, if you're MIG welding a 24-inch seam at 10 inches per minute with 15 minutes of prep: But real-world projects are rarely this straightforward. Accurate weld time calculations help: The relationship between material thickness and weld time can be calculated using the following formula: [ WT = 2. These include the length of the weld seam, the speed at which the welding is performed, and the efficiency factor, which accounts for various non-welding activities like setup and. To calculate welding time, you need to consider several factors including the length of the weld, welding speed, and the welding process being used.
