On the other hand, the welder of present embodiment 1 possess first and second consumption electrode 120,620 due to Simple shape, therefore, it is possible to easy to manufacture, and inexpensively.When repeating resistance welding, first and second consumption electrode 120, 620, cap 910 and the part to be abutted of base 920 will wear and tear.In this case, can be from Top electrode 100 and lower electricity Only unload first and second consumption electrode 120,620 on pole 600 to be polished, so as to generate the face complanation of abrasion.Throw Light operation especially simply, and terminates in a short time compared with the situation for the Top electrode polishing for constructing existing scroll chuck.It is logical Cross and repeat to polish, first and second can be caused to consume electrode 120,620 thinning, though need to be replaced by it is new, first and second Electrode 120,620 itself is consumed also cheap, therefore, it is possible to change at low cost.Because first and second consumption electrode 120,620 First and second main electrode 110,610 is only adsorbed on by negative pressure via adsorption hole 118,618, so first and Two consumption electrodes 120,620 unload and installed very simple relative to Top electrode 100 and bottom electrode 600.These are as a result, this reality Applying the welder of mode 1 can simply and inexpensively carry out what is come with the abrasion of Top electrode 100 and bottom electrode 600 Maintenance.

In addition, first and second consumption electrode 120,620 has in ring-type of the center provided with circular through hole 121,621 Shape.Therefore, the first consumption electrode 120 is uniformly abutted with the flange 913 of cap 910 throughout its whole week, in addition, second disappears Power pole 620 is uniformly abutted with the pedestal 921 of base 920 throughout its whole week.Therefore, it is possible to by resistance welding Compression stress and electric current are uniformly additional to flange 913 and pedestal 921 throughout the whole week.Should be as a result, it is possible to by the He of cap 910 Base 920 is welded uniformly in the circumferential direction, can obtain good welding quality.

As the positioner for cap 910 to be positioned in the horizontal direction, in the first main electrode of Top electrode 100 110 provided with three pieces of oscillating decks 115.The pawl 116 of three pieces of oscillating decks 115 is with the principle substantially the same with scroll chuck by cap 910 grip to be coaxial with central shaft 1a.Thus, cap 910 deviates or its deviation relative to the position of the horizontal direction of base 920 Reduction, therefore, it is possible to stably manufacture high-quality laser diode 900.

Because the oscillating deck 115 as positioner is arranged at the first main electrode 110, therefore electrode is being consumed by first When 120 polishings or replacing, it is not necessary to which positioner is decomposed or unloaded.From this point consider, first consumption electrode 120 relative to The dismounting of Top electrode 100 is also easy.This maintenance for being conducive to simply and inexpensively carrying out coming with the abrasion of Top electrode 100 is protected Support.

Due to the cap 910 being provided with the center of the first consumption electrode 120 in through hole 121, therefore insertion through hole 121 The insertion first of outer barrel 911 consumption electrode 120 and it is upwardly projecting.Therefore, filled using the positioning for being arranged at the first main electrode 110 Put, cap 910 can in the horizontal direction be positioned.

In the above-described embodiment, positioner possesses three pieces of oscillating decks 115, but constitutes the oscillating deck of positioner 115 quantity is not limited to three pieces, can be more than its, can also be fewer than its.Determine for example, only can be made up of one piece of oscillating deck 115 Position device.In this case, cap 910 be clipped in oscillating deck 115 only one pawl 116 and centre bore 111 inner peripheral surface (or First consumption electrode 120 through hole 121 inner peripheral surface) between mode be positioned holding in the horizontal direction.After positioning Cap 910 may deviate from central shaft 1a, but due to eccentric direction or offset can be usually maintained into constant, therefore with Situation about being positioned with three pawls 116 is same, and the position that can reduce horizontal direction of the cap 910 relative to base 920 is inclined From or its deviation.

First and second consumption electrode 120,620 is adsorbed in first and second main electrode 110,610 using negative pressure.This has Beneficial to that first and second consumption electrode 120,620 can be repeated with simple structure be removably held in first and second master Electrode 110,610.

When first and second consumption electrode 120,620 unexpectedly comes off from the separation of first and second main electrode 110,610, It can not be resistance welded.It is therefore preferable that possessing detection first consumes the presence or absence of the consumption electrode 620 of electrode 120 and/or second Consume electrode inspector.The structure for consuming electrode inspector is any, but for example can be by the adsorption hole to forming negative pressure 118th, 618 or the apparatus for detecting pressure that is measured of pressure of pipeline in communication constitute.In the pressure corresponding to adsorption hole 118 In the case that power detection device is not detected by desired negative pressure, it is judged as that the first consumption electrode 120 has come off, corresponding to suction In the case that the apparatus for detecting pressure in attached hole 618 is not detected by desired negative pressure, it is judged as that the second consumption electrode 620 has taken off Fall.Because the consumption electrode inspector can utilize one of the holding meanss for keeping first and second to consume electrode 120,620 Divide (that is, adsorption hole 118,618 or pipeline in communication) and constitute, therefore, it is possible to by for consuming chasing after for electrode inspector Plus number of components is suppressed to less degree, consumption electrode inspector simple in construction and inexpensive can be realized.Consume electrode Detection means is set respectively preferably with respect to Top electrode 100 and the both sides of bottom electrode 600, but it is also possible to set relative to either one Put.
