How Weather Conditions Impact Outdoor Welding Jobs

Weather matters for weld quality, worker safety, scheduling, and project planning, among other things. Experienced welding companies in Cleveland providing mobile welding services know that site evaluation is a must before any work can start. Here’s what welding services providers are thinking about when it comes to weather.

Why Weather Matters in Outdoor Welding

Simply put, outdoor welding presents challenges that shop environments do not. There are countless variables–like wind, rain, humidity, extreme temperatures, and other environmental conditions–that can be controlled and minimized or eliminated when welding is done indoors. But when done outdoors, welding is directly impacted by these factors, from the welding process and product quality to jobsite and worker safety. This is why professional welders take necessary precautions before and during a project that is being done outdoors. 

Weather Conditions And How They Impact The Welding Process

While having the right safety equipment and supplies is a must, that’s only part of the story. Successful outdoor welding is also about understanding how changing weather conditions affect the weld, materials, and people performing the work. It takes experience and problem solving skills to avoid common welding mistakes, stay safe and get the job done right. Here’s what professional welders know about how the weather impacts their work.

Wind

Excessive wind during the welding process can:

• Disrupt shielding gas
• Expose the molten weld pool to atmospheric contamination
• Contribute to porosity and other weld defects
• Make certain welding processes more difficult
• Blow sparks and debris into unintended areas

To prevent the negative effects of strong wind, experienced welders may use appropriate windbreaks or other protective measures if possible, or choose a form of welding that is better suited to the unique field conditions. For instance, stick welding (SMAW) generally handles outdoor breezes much better than gas processes and flux-core (FCAW) self-shielded wire creates its own protective gas shield. On the other hand, TIG and standard MIG welding can fail quickly in a strong wind. 

Rain, Snow, and Moisture

Precipitation of any kind can create serious concerns on a welding jobsite. Wet work surfaces can cause potential safety hazards, and excess moisture can lead to electrical hazards as well. Moisture contamination and moisture-sensitive consumables can lead to weak or failed welds, and professional welders may choose to postpone work to preserve safety and work quality. Wet clothing and PPE and reduced visibility can also make it difficult to work smoothly and react to potential risks. All in all, precipitation is one of the biggest natural enemies of outdoor welding.

Cold

Cold weather can affect both the metal and welding process itself, as materials act differently than normal when under extreme temperatures. For instance, base metals may require additional preparation and certain materials may need preheating. Very low temperatures can lead to rapid cooling that can negatively influence weld properties. When hot welds are confronted with cold weather, condensation can develop as materials change temperature, and that moisture can threaten weld integrity. Equipment and consumables need to be properly stored and handled, and it takes experience to get it right. Cold temperatures can also lead to reduced dexterity on the part of the welder, along with slower reaction times.

Heat

High temperatures create a different set of challenges, particularly for workers. Welding, and especially mobile welding, is a hot job. On top of wearing layers of protective clothing and gear, handling hot metal and hot welding equipment, outdoor welders are also exposed to the elements. In hot weather, this poses a real risk of heat stress, dehydration, and fatigue. Equipment overheating is also a common occurrence. In hot weather, welders must take time to thoroughly evaluate the worksite and plan accordingly–hydration, breaks, shade, appropriate PPE, and more.

Humidity and Condensation

While similar to precipitation, humidity and condensation can occur when there is no drop or flake falling from the sky. Humid cool air can lead to condensation as a result of the temperature difference with the hot welding material. Humidity may not seem as disruptive as rain or wind, but moisture can still create problems. Condensation on metal and surface moisture can lead to contamination of welding materials, corrosion and weakened or failed welds. Surfaces should be appropriately prepared and dry before welding begins.

Severe Weather and Lightning

Sometimes the correct decision is simply to stop work for the time being and pick it back up when conditions are safer. This is definitely the case when dealing with thunderstorms, lightning, high winds, severe heat or cold, and heavy rain, snow or ice. Minimal amounts of certain weather conditions can be dealt with and successful welding can still be done, but in the case of extremes, and any time that lighting is present, the job needs to pause. Project deadlines should never take priority over worker or jobsite safety, and any welding done during these conditions would be compromised anyway.

All of these extreme weather conditions can have negative effects on the final weld. Poorly controlled outdoor conditions can contribute to problems such as:

• Porosity
• Cracking
• Incomplete fusion
• Contamination
• Irregular weld appearance
• Reduced weld integrity

That said, less-than-ideal weather doesn't automatically mean an outdoor weld will be poor quality. Professional welding companies train and educate their welders to know how to deal with everyday variables. However, conditions must be accounted for through the correct procedures and controls, and consequences must be understood and factored in from the outset.

How Professional Welders Prepare for Outdoor Conditions

Process selection to choose the right type of welding for an outdoor project depends on the material, application, location, weather conditions, project specifications, and required weld quality. There is no one method that is always the best for outdoor work. Instead, the professional welders on a job will prepare by reviewing the projected weather conditions to know what sort of variable and changeable conditions they’ll be up against. They’ll also inspect the work area to know which fixed conditions they’ll be subjected to. Taking those various details into account, they can then select an appropriate welding process, or multiple potential processes, that would work best given their limiting criteria. They can do their best to protect the work area from wind and keep materials and consumables dry. Metal surfaces can be cleaned and prepared prior to welding, and some materials may benefit from preheating. Welding equipment should always be secured to reduce risks from wind or wet conditions, and appropriate PPE and safety gear are nonnegotiable. Experienced welding professionals will also make time to monitor conditions throughout the duration of the job, and are always ready to shift along with the weather.

Mobile welding services providers are used to dealing with challenging–and changing–jobsite conditions. They learn to put up with limited shelter in remote locations and can handle things like equipment transportation and special power requirements along with material preparation and weather protection. These are rugged folks who know what they’re up against. But at times, there’s just no match for the weather, and all the prep work and expertise in the world won’t keep you safe. In these cases, it’s better to postpone a job than to risk the worker and their work.
