DE~ATT-~n DESCRIPTION OF T~E Pk~r-~KK~v EMBODIMENT ~l .~;
The preferred embodiment, an adaptor for use with a Submerged Arc Welder generslly identified by reference numeral 10, will now be described with reference to FIGURES 1 through 8.
. ' ,,.
Referring to FIGURE 1, adaptor 10 includes a wire feed tube 12 and a flux feed tube 14. Wire feed tube 12 is a straight tube at least one foot in length and can be as much as ten feet in length. Wire feed tube 12 has a first end 16, a second end 18, an exterior ~urface 20 and an interior bore 22 that extends between first end 16 and second end 18. It i8 preferred that wire feed tube 12 be made out of a copper alloy material with high thermal conductivity. This enables heat within wire feed tùbe 12 to be rapidly dissipated. As the length of adaptor 10 increases it i8 important to dissipate heat as adaptor 10 must maintain its rigidity. Should the material out of which wire feed tube 12 is constructed soften due to excess heat buildup, a sagging will occur. It will be understoodthow important maintAi ni ng rigidity is when welding inside long tubular objects pf restricted diameter. It has been found that the electrical characteristics of copper alloy allow enough power to be run through wire feed tube 12 to allow the melting of wire sizes ranging from .035 to .093 without .
, .. . . . _ . .
2166~96 _ 4 melting or other adverse affects due to re6istance. Bxternal threads 24 are provided on exterior surface 20 at first end 16 of wire feed tube 12. This enables first end 16 of wire eed tube 12 to be attached by means of a nut 26 to a wire feeding mechanism of a submerged arc welder (not shown). Internal threads 28 are provided within interior bore 2Z at second end 18 of wire feed tube 12. Internal threads 28 provide a mean~
for attaching a tip 30 to second end 18 of wire feed tube 12, as illustrated in FIGURES 6 throuqh 8. Referring to FIGURE
1, flux feed tube 14 is at least one foot in length and can be as much as ten feet in length. Flux feed tube 14 has a first end 32, a second end 34, an exterior surface 36 and an interior bore 38 that extends between first end 32 and second end 34.
It is preferred that flux feed tube 14 be made out of a non-corrosive stainless steel material. During the proce~s of arc welding, air with flux feed tube 14 is surrounded by hot air originating from the vicinity of the weld. This results in condensation occurring within flux feed tube 14 which results in corro~ion and, ultimately, a restriction of the flow of flux through flux feed tube 14. The use of non-corrosive material, such as stainless steel, eliminates the corrosion problem.
Stainless steel is preferred due to the smooth surface it provides. This smooth surface allows flux to be delivered under low pressure, which reduce~ or eliminates dangers associated with pressure blow out at second end 34. This el;m;nAtes the need for any protective housing or shroud over second end 34. In addition, the mechanical strength of stainless steel provides the stiffness required for lengths approaching 10 feet. Sagging problems that re6ult in surface dragging and adversely effect weld appearance and quality are not encountered. Flux feed tube 14 is disposed Lmmediately adjacent and substantially parallel to wire feed tube 12 with ~econd end 34 of flux feed tube 14 adjacent second end 18 of wire feed tube 12. Referring to FIGURES 2, ~lux feed tube 14 has a primary axis 40. Fir8t end 32 of flux feed tube 14 is angularly offset from primary axig 40. This enable6 attachment of first end 32 of flux feed tube 14 to a source of flux 216649~
;
without interference from wire feed tube 12. This is further illu~trated in FIGURE 3 and 4. Referring to FIGURES 4 and 5, an in~ulating sheathing 42 made out of a woven glas~ material covers both wire feed tube 12 and flux feed tube 14. This ~
5 maintain6 wire feed tube 12 and flux feed tube 14 in parallel , relation. Beneficial results have been obtained using a woven f glass material that comes in a tape format sold commercially under the Trademark "THERM0-CHEM". The tape iB wrapped around wire feed tube 12 and flux feed tube 14 to complete insulating 10 sheathing 42.
The use and operation of adaptor 10 will now be described with reference to FIGURE8 1 through 8. In order to use adaptor 10, a tip 30 appropriate for the job i~ selected and secured 15 to second end 18 of wire feed tube 12 by means of internal threads 28. First end 16 of wire feed tube 12 is attached to a wire feeding mechanism of a submerged arc welder (not shown) by means of nut 26 and external threads 24 on exterior surface 20. First end 32 of flux feed tube 14 is attached to a source 20 of flux. Referring to FIGURE 6, adaptor 10 is illustrated in the proces~ of completing a weld 44 within interior bore 46 of tubing 48. Adaptor 10 is also illustrated in the process o~
completing an exterior surface weld 50. Referring to FIGURE
7, adaptor 10 i6 illu6trated in the process of completing a weld 52 within a blind bore 54. It i8 to be noted that the configuration of tip 30 which i8 selected changes with the application. Referring to FIGURE 8, a workpiece 56 is illustrated which in the process of having an attachment 58 welded to it. The bulk of workpiece 56 restricts access to a weld, generally indicated by reference numeral 60. Two alternative approaches to completing weld 60 are illustrated.
It will be apparent to one skilled in the art the advantage~ to be gained through the use of adaptor 10. The ability to change the configuration of tip 30 provides a number of advantage8 in and of itgelf. Different ~izes of tips are commercially available which allow8 many wire sizes to be used 2166~9~
_ 6 -with the fiame welding apparatus. A variety of tip configurations are available, which allows weld bead manipulation to achieve different ~ize and shape. Tip~ can be replaced without dismantling of the arc welding apparatu~ which greatly decreases production down time. Short circuits and burn back are a common problem with submerged arc welding.
When this occurs, only tip 30 need be replaced to restore the ~
equipment to proper working order. The fact that no housing `s or shroud i~ required also provides advantages. Tip 30 is visible to the operator at all times. This enables greater accuracy in tip placement, which results in higher quality j!
welds. Without a hou~ing or ~hroud, adaptor 10 is much less cumbersome an~ can more readily be used in restricted areaæ
such a~ small bore tubing and fittings. The u~e of two ~-independent parallel feed tubes also provides advantages. If one of the feed tubes should become damaged due to mi~h~n~ling, ~hort circuiting or wear and tear; it can be easily replaced without major expense. Wire feed tube 12 i~ straight. This allows any ~ize wire to be guided through by the drive wheel wire feeding mechanisms on conventional equipment. This is of increasing importance the longer adaptor 10 becomes. When guiding a wire 10 feet through wire feed tube 12, any bend~ or curves in the welding wire would cause enough friction to lodge the wire inside the arc welder. This also allows for various sizes of wires to be used in the same wire feed tube 12 simply by changing tip 30. Nut 26 and external threads 24 which are provided on exterior surface 20 at first end 16 of wire feed tube 12, allow for quick hook up to conventional welding equipment. It is a rigid form of attachment. As previously stated, this is important to enable adaptor 10 to reach deep into restricted inner diameter tubing without ~agging.
Although adaptor 10 has been illustrated in FIGURES 6 through 8, in a relatively limited number of welding application~, it will be appreciated that adaptor 10 is extremely versatile and can be uged for external surfacing, external seam weldB, internal Burfacing, internal seam welds, attachment welds, and the like. All these applications can be accomplished with adaptor 10 in a horizontal, vertical or inclined position. All these application6 can be accomplished ,t whether the workpiece is fixed in a stationary position or 5 rotatably mounted. It will finally be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the ¦ inventlon as hereinafter defined in the Claims.
