Again a viable option,though timely. Looking for a simple quick solution easily applied in the field.
Not concerned with structural strenght,as there is no structural demands on area, or adjoining areas.
No they are not gear castings.
Thank you for suggestion of wrap around heaters.
Am trying to establish if there is a rod that can be used with out haveing to post/pre heat treat. The area of weld is non structural.
GRoberts- you say "If you are doing one of the exceptions, you can use...
The castings are large (2000lbs) and in a remote area. We will do some weld repair to build up non critical areas of the casting.
I would like to do the repair on the shop floor. The castings will then be placed in operation (600-800 deg F)
Pre and Post HT would be limited to shop capability.
Good afternoon:
I am looking for proper weld rod to use on ASTM A 217 WC 6 cast alloy. Castings are hightemperature use, not used pressure containing service.
Best Regards,

Good Morning:
I am looking for High temp stainless alloy for use in a reducing envirnment, operating temperatures of 2550 F. Looking for cast specification.

Thank you gentlemen for your assistance.
We will hone out bore, freeze shaft.
Existing bore is1.624 +000-.002 Existing shaft is 1.6250 +.0007-0000
will look at what appropriate bore Dia should be for slip fit in field.

Yes, this is an option, though timely due to hub thickness. Have considered opositie and placing shaft in liquid nitrogen.
will .002 be the difference between achieving a slip fit, and a press fit.
Thank you
Hub- ASTM A 27 Grade 60/30
Shaft- probably 1045, at best 4140 finish 63
Hardness- don't know
Function- shaft to wheel.
Typically shaft is welded on back side, one inserted into the bore of the frame. This practice evolved as field people did not have the machinery to actually make a press fit...
KENAT-
1.625 is base dim.
What tolernce would be an acceptable interference fit, forced by pounding. (lightly)
What tolerence would be acceptable press fit.
We are talking about a fit that can be done in the field with a hammer and a jig to cover the shaft while pounding it in.
Thank you

Hi
What is the acceptable tolerance of a shaft for a bore that is 1.6242 +000/-.0002.
Shaft diameter being 1.625.
If the bore is 1.624 +000/-.0002 does this make a big difference.
In order to have a forced fit, not pressed, and not sliding right on, how much tolerance should be between the...
