焊接專用設備点焊的工艺过程为开通冷却水;将焊件表面清理干净，装配准确后，送入上、下电极之间，施加压力，使其接触良好;通电使两工件接触表面受热，局部熔化，形成熔核;断电后保持压力，使熔核在压力下冷却凝固　形成焊点;去除压力，取出工件。

焊件預備及安裝：鋼焊件焊前須鏟除全部髒物、油汙、氧化皮及鐵鏽，對熱軋鋼，Z好把焊接處先經過酸洗、噴砂或用砂輪鏟除氧化皮。未經清理的焊件雖能進行點焊，但是嚴重地下降電極的運用壽命，一起下降點焊的出産功率和質量。關于有薄鍍層的中低碳鋼可以直接施焊。

在焊接中低碳鋼時，點焊機可利用強規範焊接法(瞬時通電)或弱規範焊接法(長時通電)。在大量生産時應采用強規範焊接法，它能提高生産效率，減少電能消耗及減輕工件變形。焊接電流決定于焊件之大小、厚度及接觸表面的情況。通常金屬導電率越高，電極壓力越大，焊接時間應越短。此時所需的電流密度也隨之增大。

He hand b'long coldee, all same like ice, His suggestion was adopted, and they at once set about their work, determined to write two hours daily till they had described Canton so fully that their friends would know exactly what was to be seen there. They divided the work, as they had done on previous occasions, one of them making a description of a certain part of their route, and the other taking another portion of it. When they were through with it, they put the two stories together, and found that they fitted to perfection. Here is what they wrote: "If you know where she lives----" Charlton began. Maitrank grinned in sinister fashion. 4. The value of handling machinery, or the saving it effects, is as the constancy with which it operates; such machinery may shorten the time of handling without cheapening the expense. Those words gave me a shock, for I had heard that German officers always tried to encourage the Belgians in their wrong opinion about the alleged violation of Netherland neutrality, but I had not been able to believe it. With an innocent face I asked the officer: A hundred little things might have told me, if I had had any wits. "I do, though," she said perversely, as she bent her[Pg 48] head and tried to put into order the tumbled mass of her hair. "I am going at eleven o'clock." "He's coming back from Tombstone with some money, ain't he?" "Co. Q, 200th Injianny Volunteers." After some thought Cadnan asked: "Who can be his own master? It is like being your own mate." Alice rose too, and for a moment he was surprised that she did not try to keep him; instead, she said: The Squire had called it blackmail and made a terrible fuss about it, but from the first the issues had been in Reuben's hands. A public scandal, the appearance of Flightshot's heir before the county magistrates on the charge of shooting a cow in a drunken frolic, was simply not to be contemplated; the only son of the Manor must not be sacrificed to make a rustic holiday. After all, ever since the Inclosure the Fair had been merely a matter of toleration; and as Backfield pointed out, it could easily go elsewhere—to the big Tillingham[Pg 455] meadow outside Rye, for instance, where the wild beast shows pitched when they came. All things considered, resistance was not worth while, and Flightshot made its last capitulation to Odiam. But in this instance his exultation was of short duration, for one, who had leaped from the battlements of the Tower unheeded, and had swam along the river unharmed, approached Sir Robert Knowles, who was riding something in advance of the party, and with his saturated apparel bearing testimony to his assertions, announced the stunning intelligence that the Tower was at that moment in the possession of the commons. This brave defender of the fortress was Calverley. But lo! when Calverley's prison door was opened, for the purpose of conducting him to the hall, he was not to be found! It was to no purpose that the baron stormed and threatened, no trace of Calverley could be discovered; but John Byles was brought forward, and, upon being confronted with his own servitor, and promised that if he made a full disclosure, the punishment of the crime should be remitted, he confessed all with which the reader was made acquainted in the early part of the tale. The question of poisoning was then put, but Byles had cunning enough to remember that no one was privy to this but Calverley, and as it might peril Mary's life, he stoutly denied all knowledge of the matter. Mary Byles, who had also been kept in durance, was then introduced, but she was more collected than on the preceding evening, and would admit nothing. She knew not any thing of the buck—and she could say nothing more respecting the poisoning than she had already said at Gloucester, and the supposition of Edith's innocence, was compelled to rest upon the servitor's oath, who swore that he had heard Mary say, on the evening she returned from Gloucester, what Sir Robert had repeated. This, coupled with the circumstance that, together with the poisoning, Mary had denied what her husband had admitted, and what could not have happened without her knowledge, brought sufficiently conclusive evidence to convince every one that Edith had died a martyr to Mary's cruelty or carelessness.
