22. WELDS FIRM ( BRASSING ) Welds firm or braising interpreted as :
Tacking on nonspecific metal or differs in type ( iron, nipple, copper ) applies bar stay to weld ( as its(the deliverer ), where temperature or point of the liquid and joint is lower than substance which will be bound it.
Teknologi dan Rekayasa

23. Some things needed to be paid attention are:
1. Area which would be in bracing must be
accurate in plane and level
2. Plane (capillarity space) from
both of areas 0,05 - 0,2 mm depend on height to creep ( speed ) happened
3. Both of sides ex- cross section ( plane
welded ) must be in spacing out a few, to
water down entering liquid flow
Teknologi dan Rekayasa

24. 4. Surface area of equiamplitude must be free of cake or rust ( metals ) Means : - There shall not oxidation - There shall not impurity - May not be oily 5. Brazing temperature of 4500 C
Teknologi dan Rekayasa

25. 6. Point of material liquid adds must be reached according to brazing temperature 7. Borax must be dabbed at brazing plane surface and material adds
Teknologi dan Rekayasa

26. 8. Weld flame ( slack ) liquefies material to add and push, according to temperature at the area. Heating at weld area may not be too stripper, because material adds can be combustible
9. After welder hence substance :
- May not be moved ( peripatetic )
- May not be in making cool in forces
Because at this brazing its(the base material is
unegual hence expansion happened nor same.

27. PIPE CONNECTION MODE OF ACTION
1.Material and work substance is drawn up [by]
2.Pipa copper in welding( bracing ) must be cleaned former of its(the equiamplitud surface from oxidation by using penetrate / sandpaper
Teknologi dan Rekayasa

28. Tip of division which would be in welding must be correct - clean
After in sandpaper / cleaned may not
be held direct hand
Teknologi dan Rekayasa

29. 3. Matter
"Pipe which would be in welding is given [by] cleaner fluid / bunk
"Enter one by one at fitting which has been provided (where before all also in giving bunk / cleaner also ).
Teknologi dan Rekayasa

30. For tee, the brazing was at the same deconvolution because heat time at the same pipe, and intake of material adds into aperture fitting must be flatten and good
Teknologi dan Rekayasa

31. JOINT MODE OF ACTION JOINS WITH OTHERS
Preheats both equiamplitude surfaces of work substance ( join others, which has been given fluid ( bunk ), finite of fluid runs dry and equiamplitude surface of work substance starts squeezing
Heating of work substance so squeezing and rather releases fluid
Teknologi dan Rekayasa

32. when it has started squeezes material to add puts into plane surface to weld ( doesn't directly is hit (the fire). Hence through the area temperature flow, material adds will be melt.
Teknologi dan Rekayasa

33. Then pushes the fluid and follows the direction of its(the flow along the length of joint ( seam )
Teknologi dan Rekayasa

34. If welding ( Bracing ) has, hence it takes work substance, cleans and controls the result of workmanship.

41. At bends with small radius often happened bends with oval form.
As for its the causes :
1. Heating of too hot pipe
