Intermittent Welding (also known as intermittent welding or spark welding) is a process that creates discontinuous welds by welding in sections. Its core characteristic is the intermittent operation of welding one section and then resting another. Its core value lies in balancing efficiency and structural stability.

Core Process Features

Heat Control: By intermittently switching the current, heat input to the weld area is precisely adjusted, reducing the heat-affected zone (HAZ). This makes it suitable for heat-sensitive materials such as cast iron and high-carbon steel.

Efficiency Improvement: Intermittent welding reduces transient high temperatures in the weld zone through alternating heating and cooling, accelerating welding speed and improving production efficiency.

Stress Optimization: The interval design of intermittent welds evenly distributes stress, avoiding the localized stress concentration caused by continuous welds.

Energy Saving and Environmental Protection: Controlling current consumption saves energy and reduces harmful gas emissions.

Intermittent welding technology, with "low heat input" as its spear and "high economy" as its shield, has become an irreplaceable solution for deformation-sensitive scenarios; it has also become an innovative tool for dealing with thin plate structures, special-shaped components, etc. in industries such as steel structures, ships and energy equipment.
