Rotary Friction Welding

We are currently fabricating two mammoth steel weldments that will be integral parts of the largest Rotary Friction Welder ever built. This machine will have twice the inertia capacity of any other machine on the planet!
Rotary friction welding is a joining process which involves holding one part stationary while rotating the other. Under extreme pressure, the two parts are forced together, creating sufficient friction and heat to reach the forging temperature without melting. When the weld interface cools, the two parts are bonded at the molecular level and the welding process is complete.
This enormous machine will be used by the Aerospace Industry in the United States to build next generation jet engines that will burn fuel hotter than ever before. Hotter engines create higher thrust capacity, while at the same time reducing fuel consumption and overall costs.
The two weldments being manufactured at J & J are the Lower Base and the Head Stock. The Lower Base stands 42” tall x 134” wide x 368” long and weighs 126,000 pounds. The Head Stock will be 70” x 172” x 174” and weigh 165,000 pounds. Almost ten thousand pounds of welding wire will be used by our AWS D1.1 certified welders to join A36 steel plate up to 21” thick. Together, these parts will require approximately 1,600 labor hours to complete.

Safety First in Steel Fabricating Shop

At J & J Burning and Fabricating Company, we place a great emphasis on the safety of our employees. In an effort to keep the inherently dangerous world of a steel fabricating facility as safe as possible, we have enlisted Safety Consultants from the Michigan Occupational Safety and Health Administration (MIOSHA) to assist us in refining our practices.

Partnering with these outside experts has been vital in keeping both management and manufacturing employees in a “Safety First” mindset. Using both MIOSHA mandated and our own internal records, we track all injuries and accidents. Each one is investigated, recorded, and discussed at our monthly safety meetings. We try to learn from past mistakes and revise practices or update equipment to ensure that the same mistake does not happen twice. We also have two shop supervisors who were certified through a MIOSHA General Industry Safety course. They have been able to take what they learned and tailor it to meet the needs of our metal fabricating environment.

The national Occupational Safety and Health Administration (OSHA) was created in 1970 to set and enforce regulations to ensure that all private sector workers in the United States have safe and healthy working conditions. OSHA is part of the United States Department of Labor. MIOSHA is our statewide branch. According to the State of Michigan website, MIOSHA works with employers and employees to prevent workplace injuries, illnesses and fatalities. Health and safety activities include setting and enforcing standards; providing safety and health training and education; and working with partners to develop innovative programs to prevent workplace hazards.

With a concentrated effort, J & J Burning has reduced injuries by 88% in the last three years. We are very proud of the fact that we have an injury rating below the steel fabrication industry average.

Precision Fabrication and Assembly

Fully fabricated, machined and assembled frams for the Glass Manufacturing Industry.

Fully fabricated, machined and assembled frames for the Glass Manufacturing Industry.

J & J Burning and Fabricating Company fabricated and assembled 40 Overhead Cooler Cart Frames for a world leader in architectural and automotive glass manufacturing. These precision steel fabrications are made from certified A36 plate, channel, beam and angle, along with ASTM A500 steel tubes. Each one of the 350 pound frames is made up of 46 separate details and welded by the experienced team of AWS D1.1 certified welders at J & J Burning. After machining, 137 additional details were assembled to the frames. The complete project was delivered to the customer on-time and defect-free.

These intricately assembled frames are critical components of a float glass line. Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and various low melting point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces. The glass flows onto the tin surface forming a floating ribbon with perfectly smooth surfaces on both sides and an even thickness. As the glass flows along the tin bath, the temperature is gradually reduced from 1100 °C until the sheet can be lifted from the tin onto rollers at approximately 600 °C. The glass ribbon is pulled off the bath by rollers at a controlled speed. Variation in the flow speed and roller speed enables glass sheets of varying thickness to be formed.
