Welding and Fabrication
In acquiring the wide range of capabilities required to manufacture machines, Manifold & Phalor, Inc also provides welding and fabricating services.
An example of structural welding is in this tunneling machine. Forces applied by this machine exceed 200 tons putting huge stresses on the 2” thick welded structure.
In many cases, weldments require stress relieving after fabrication. The size of many weldments, or the type of materials used in construction, may prevent the use of thermal stress relieving in completing a weldment. Vibratory stress relieving is an effective alternative when used on weldments and castings of any material. Shown below is vibratory stress relieving applied to a 35’ long, 10,000 lb. machine frame weldment.
Weld repair of machine parts is often the only alternative to salvaging large and expensive items. Shown below is an 80 year old, 2 piece, 8 foot diameter cast iron flywheel for a large air compressor. The bore had become worn over time and had to be repaired by welding and remachining the bore to fit the shaft.
While steel structural welding is at one end of the spectrum of metals joining, stainless steel sanitary welding represents the other end. Sanitary welded parts used in food processing plants are particularly difficult due to the requirement that the surfaces are defect free to prevent trapping food particles. Shown below is a precision valve weldment used in food handling equipment.
In addition to the welding of mild steel, other materials that are joined on a daily basis include aluminum, alloy and tool steels, cast iron, stainless steel and copper based alloys.
