Ajax TOCCO Retrofits Customer’s Existing 35kW Induction Heater With Remote Mounted Low Profile Non-Contact Weld Preheat Inductor and Transformer
Ajax TOCCO Magnethermic recently supplied a forestry products manufacturer a compact remote transformer and low profile heating inductor to be used for preheating prior to GMAW. These items were sold as a field install kit that are compatible with and utilize the customer’s existing induction heating cables and accessories. The heating inductor floats above the weldment without making contact. Versatility and utilization of the 35kW induction heater heater were immediately increased.
The customer had a need to be able to heat a rotating weldment with limited space between welds. Existing weld preheat inductors that roll on top of the weldment would not fit between the weldments forcing the customer to rely combustion heating technology (torches).
Not satisfied with the safety issues and inconsistency associated with combustion heating, the customer reached out to Ajax TOCCO for a solution to their challenges. Ajax TOCCO was able to quickly analyze their process and custom build a compact, non-contact weld preheat inductor that provided pin point heating accuracy, rapid heat rates, and repeatable traceable results. The inductor only measures 1 inch x 6 inches and had a 12 inch reach. The size of the inductor is orders of magnitude smaller than existing weld preheat inductors currently offered for moving/rotating parts. The compact inductor can be located anywhere the weld torch can be positioned.
The heating inductor is used in conjunction with Ajax TOCCO’s exclusive Slimline hand held transformer. This transformer attaches to the end of existing liquid cooled induction extension cables. The purpose of the transformer is to magnify the electrical resistance of the low profile weld preheat inductor in order to maintain exact optimal safe operating parameters for the 35kW induction heater.
Ajax TOCCO air cooled induction weld preheat systems offer the many advantages including:
* Controlled Cooling Rates
• Increased Penetration
• Increased Feed Rates
• Improved Quality
• Reduced Consumables
High frequency induction heating cables can be configured for round, flat or irregular surfaces. No tools are required for installation and use. All electrical connections are made with quick disconnects and circular military style connectors. Other applications include bearing/sleeve shrink fitting, coatings curing, coatings removal, die heating and bulk heating applications.
