Why use Metal Locking instead of welding?

Metal Locking Procedure

Leaves machine surface true and unwarped
Readily machineable across area of repair
No pre-heating or stress relief necessary
Cold repair presents no fire hazard in restricted areas
Dissimilar metals readily joined
Eliminates high stress concentration by re-distributing such stress
Ductility of high nickel locks used renders area more shock resistant and
provides dampening effect
High nickel content in locking material makes repair resistant to chemical
corrosion and acceptable for food products

Metal Locking procedure

Welding Procedure

Causes warpage and misalignment and often damages machined surface
Machining often difficult, sometimes impossible, at fusion area
Pre-heat and post repair stress relief usually necessary
Involves fire hazard
Difficult to weld dissimilar metals
Introduces stresses and hard spots particularly at fusion area
Causes brittleness, lowers shock resistance and dampening effect

A final word about the process of 'cold' repair:
It must be emphasized that we do not imply that this always is a substitute for the welding procedure, particularly in steel. Certainly welding has its place, but it does approach its limitations in the field of cast iron.

What specific items do we repair and/or rebuild?

Industrial Components - gears (including worn or broken teeth), flywheels, clutches, shafts, rollers, crankshafts, rams, gibs, ways, pitmans, paddles, couplers, etc.
Compressors - frames, pistons, cylinders and heads
Pumps - water, steam, gas, oil, and air
Engines - blocks from automotive to marine to locomotive, cylinder heads, transmission housings and gear boxes
Manipulation - forklift; boom and support repairs (bent or broken), crane wheels and gearboxes

How long does a Metal Locking repair last?
Metal Locking repairs are permanent. Proper design and application assure that the strength of the repair will meet or exceed the original operating conditions.

What information do I need to supply in order to receive a quotation or estimate?
For a ballpark estimate, digital photographs and phone correspondence are typically sufficient. If the inquiry relates to an on-site repair, we will need a physical address so that we may estimate travel expenses. When digital photographs are not available, faxed drawings may suffice.

Is there any cost associated with a quotation?
Typically there is no cost associated unless an inspection visit is required. At that time we will ask to be compensated for our travel expenses only.
