What's the difference between TIG and MIG welding?
TIG welding uses a tungsten electrode and produces cleaner, more precise welds ideal for thin materials and artistic projects. MIG welding uses a wire feed and works faster, making it better for thicker metals and structural work. At Pittman's mobile welding, we use both techniques depending on your project needs.
Can you weld aluminum and cast iron together?
Aluminum and cast iron require different welding approaches due to their distinct melting points and properties. Aluminum needs specialized TIG techniques, while cast iron often requires preheating and specific rod selection. Pittman's mobile welding has the equipment and expertise to handle both materials for farm equipment and custom fabrication projects.
How does mobile welding work for roadside repairs?
Mobile welding brings professional equipment directly to your breakdown location, whether on the road or at your farm. We use portable generators and stick, TIG, or MIG welders to perform on-site repairs for trucks, trailers, and heavy equipment without needing a tow.
What affects the cost of structural welding projects?
Material type, project size, weld complexity, and load-bearing requirements all influence structural welding costs. Steel thickness, joint accessibility, and whether the work involves building frameworks or bridge components also play a role. At Pittman's mobile welding, we assess your structural needs to provide accurate pricing.
When should farm equipment be welded versus replaced?
Welding is cost-effective when the frame or structure remains sound and only specific components like brackets, hitches, or loader arms need repair. If the base metal is severely corroded or cracked throughout, replacement may be safer. We evaluate agricultural equipment to recommend the most durable and economical solution.
Can trailer hitches be strengthened with custom welding?
Yes, trailer hitches can be reinforced with heavy-duty steel plate additions or gussets to handle increased towing loads. Custom welding also allows for modifications like adjustable heights or specialized receiver designs. Pittman's mobile welding fabricates and strengthens hitches for commercial trucks and heavy trailers.
What's the biggest mistake people make with welding repairs?
Many people attempt temporary fixes with inadequate penetration or improper filler material, which fails under stress. Using the wrong welding method for the metal type or skipping surface preparation also leads to weak joints. Professional mobile welding ensures proper technique and material selection for long-lasting repairs.
How long does structural welding last on building frames?
Properly executed structural welds can last the entire lifespan of a building, often 50 years or more, when protected from corrosion. Quality depends on joint design, welding technique, and post-weld treatment like painting or galvanizing. At Pittman's mobile welding, we focus on strength and durability for long-term infrastructure performance.
Do you need special equipment for on-site welding?
On-site welding requires portable generators, mobile welding machines, proper shielding gas cylinders, and safety gear designed for field conditions. Professional mobile services also carry backup equipment and materials to handle unexpected project needs. Pittman's mobile welding comes fully equipped for repairs and fabrication at your location in Mayfield and surrounding areas.
Can rusted farm equipment still be welded safely?
Yes, but rust must be removed from the welding area first to ensure strong penetration and prevent porosity. Surface preparation includes grinding, wire brushing, or sandblasting to expose clean base metal. Pittman's mobile welding preps agricultural equipment properly before welding to maintain structural integrity.
What materials work best for custom fence fabrication?
Steel tubing and aluminum offer durability and corrosion resistance for custom fences, with steel providing strength for livestock containment and aluminum working well for decorative applications. Material choice depends on your fence purpose, terrain, and maintenance preferences. We fabricate custom metal fences tailored to farm and residential needs.
How do Kentucky winters affect outdoor welding work?
Cold temperatures in Mayfield and western Kentucky can cause moisture condensation on metal, leading to weld defects if not properly dried. Preheating materials and using low-hydrogen electrodes helps prevent cracking in cold weather. Pittman's mobile welding adjusts techniques based on local conditions to ensure quality outdoor repairs year-round.
