What is a cold shut link?
Cold shut links are designed to repair low grade chains or attach fittings in the field in just a few minutes. These handy links come with a corrosion resistant zinc plating and install easily between two links or a link and fitting with just a hammer.
What do you mean by cold shut in forging?
Definition of cold shut (Entry 2 of 2) 1 : the freezing of the surface of liquid metal during the pouring of an ingot or casting due to interrupted or improper pouring also : an imperfection thus caused. 2 : the imperfect weld caused in a forging by the inadequate heat of one surface under working or by an oxide film.

What is a cold shunt?
A cold shut is a fault in the surface of a piece of metal caused by two streams of molten metal not joining properly when the piece is being cast.
What is a forging lap?
Lap — A surface irregularity appearing as a fissure or opening, caused by the folding over of hot metal, fins or sharp corners and by subsequent rolling or forging (but not welding) of these into the surface.
What is cold shut and Misrun?
Pouring metal defects include misruns, cold shuts, and inclusions. A misrun occurs when the liquid metal does not completely fill the mould cavity, leaving an unfilled portion. Cold shuts occur when two fronts of liquid metal do not fuse properly in the mould cavity, leaving a weak spot.
How do you stop porosity in casting?
Gas porosity can be eliminated through good mould design or by introducing nitrogen into the aluminium metal before the liquid pour. HiPping can also be used to eliminate small amounts of porosity inside the casting.
What causes Misrun?
A misrun occurs when the molten metal freezes before it reaches all parts of the mould cavity – which leaves a completely unfilled part of the mould. Both problems can lead to weak spots in castings, so it is important that we prevent these issues from occurring during production.
What is cold shot in casting?
Cold shots are ball-, drop- or pearl-shaped inclusions which are only loosely attached to the metal. In any casting method, cold shots can result from turbulences during the casting process or from spraying effects in the mold. Some metal parts harden prematurely and have the form of drops or balls.

What is drop forging?
drop forging, Process of shaping metal and increasing its strength. In most forging, an upper die is forced against a heated workpiece positioned on a stationary lower die. If the upper die or hammer is dropped, the process is known as drop forging.
What is warpage in forging?
Warpage – Term generally applied to distortion that results during quenching from the heat-treating temperature; hand straightening, press straightening, or cold restriking is employed, depending on the configuration of the part and the amount of warpage involved.
What is Fullering in forging?
“Fullering,” more generally, refers to any forging process creating a sharp transition in cross-dimensional area; with care, some types of fullering can be achieved using only hammer and the edge of the anvil (which acts as the fuller).
How do you compensate casting shrinkage?
We compensate for shrinkage of gold by veneering the surface of the die with a sheet of copper applied by electroplating. The thickness of the copper sheet is regulated in accordance with the amount of the shrinkage of the gold to be com- pensated for.
How can we prevent Microporosity?
Every process engineering measure which can be avoided by overtreatment of iron and restricted by Mg scattering reduces the microporosity tendency of the iron.
How do you prevent scab failure?
Measures for prevention:
Reducing occurring compressive stresses by: fast and even mold filling. Avoiding too wet mold materials. Use of mold material additives which dampen the quartzsand expansion by softening or burning (e.g. neutral or basic swelling binders for cast steel)
What is a hammerlock shackle?
Description. Used as a safe alternative to welding, the hammerlock shackles provide rated attachment of safety chain to the trailer drawbar on a suitable rated safety chain attachment point.

What is a hammerlock chain?
Hammerlock coupling links are used for attaching chain to master links, eye type hooks, installing a new. branch to a sling or just connecting components during chain sling fabrication.
Are hammer locks legal for towing?
Only one rated shackle is permitted per chain – you cannot extend a chain with shackles, rated or not! But you can use a hammerlock (pictured above. If your trailer is over 3.5-tons ATM then it’s illegal to use galvanised chain (and shackles).
