Low temperatures can affect the strength of metal and the effectiveness of various welding supplies. However, professional welders still need to complete their work, and even hobbyists shouldn’t have to give up their projects for an entire season. Here are some things to know if you plan to weld in cold temperatures. 

Questions About Welding in Winter, Answered

What safety considerations should I make when welding in winter?

Cold temperatures can affect your circulation and lead to less feeling in your fingers. Since welding requires precision and dexterity, wear gloves to keep your hands warm, and take breaks when you feel any numbness. Additionally, use caution when heating garages or workshops with propane or gas heaters; these require ventilation since they create toxic fumes, so leave the door open enough to maintain oxygen levels. 

How can I protect my welding supplies?

Water-cooled torches and welding equipment may freeze if left in the cold. Electronic equipment and batteries can also be adversely affected by cold, since more power is required to get equipment up to a high temperature. Store this equipment in a heated garage or workspace when not in use. 

Does pre-heating make metal less brittle?

Pre-heating involves raising the temperature of metal before welding. This makes the material less brittle, and it prevents it from cooling too quickly afterward, since extreme temperature shifts may cause cracking. Pre-heating can be done in a furnace or with a heating torch or electric heater. 

What steps can I take to improve the strength of my welds?

In addition to pre-heating and protecting your welding tools, consider arranging insulated blankets over your welds once completed to prevent the material from cooling too quickly. When possible, perform welds in a heated workshop, or use mobile heaters to raise the surrounding temperature slightly. When welding outdoors, try to complete work on days when the temperature is above freezing. Otherwise, more heat may be necessary to weld very cold metals.
