Manual start and crater control features allow the user to gradually ramp up and ramp down the weld parameters at the beginning and end of the weld, providing additional control for fine tuning the bead profile and reducing cold lap
, crater cracking and consumables costs.
Since installing the ladle, Dotson has noticed cold lap
, slag and similar pouring defects have been virtually eliminated.
Although these pouring temperatures are considered high for magnesium, the goal was to completely fill these patterns without cold lap
The objective is to detect any pre-existing condition at the origin that may have led to crack formation (such as an inclusion, cold lap
, micro hot tear, etc.
Since the TENBLOC alloy is mixed to precise grades and chemistry, it is virtually guaranteed to eliminate chemical segregation, slag, blow hole, cold lap
and shrinkage defects common to other solid cast inserts.
Produced to a precise shape and size, block weight is closely controlled resulting in minimal slag while reducing oxidized blow holes, cold lap
and shrinkage defects.
Other types of defects such as cold laps
, cold shots and re-oxidation products, previously caused by metal flow, also were significantly reduced.
of Birmingham, identified that it must be able to predict the occurrence and location of all the problems that occur during the casting process including gas porosity, shrinkage porosity, cold laps
and shuts, sand erosion and hot tearing.
